6 Properties of Solids, Here’s an Explanation & Examples

Properties of Solids – Sinaumed’s must be familiar with the shape of objects, starting from solid, liquid and gas. In everyday life we ​​often encounter these three forms of objects. However, Sinaumed’s needs to know that every object has its own characteristics, types, and characteristics. That is why the three forms also have their own symptoms of change. For example, the nature of solid objects will experience a change in form that is different from liquids and gases. 

Because it has its own symptoms, Sinaumed’s needs to understand each of the three forms of matter. Sinaumed’s probably already studied material form of objects from elementary school to high school, which was then developed with more complex physics and chemistry material. The material form of this object then becomes the basic material and theory for studying various kinds of changes in shape in physics and chemistry. 

To understand this, Sinaumed’s can start to recognize the properties of solid objects, starting from the understanding, characteristics, changes in form, and examples of objects around our environment, such as the following: 


Solids are forms of matter that have a solid form with mass and occupy a certain space or volume. The most obvious property of solids is that they have a fixed shape and size before being given action to make changes. Solids also have a very strong attraction between molecules so that the shape of this solid object can have a fixed volume with a large molecular density. 

If a solid object is put in a container or place. Then the shape will remain as before, not following the shape of the container, unless it is given energy or heat to change, either to liquid or gas. This is of course very different from the properties of liquids and gases whose form will follow the shape of the container if placed in a particular container. 


The definition of a solid is a material that has a shape and also a volume or space occupied by certain solids, liquids, and also gases. There are two main ways in which solid particles can be arranged, namely in neatly ordered rows and in an erratic arrangement. Where solids whose particles are arranged in regular and neat rows are usually called crystals. Examples of crystals include diamonds, metals, ice, and salt crystals.

Meanwhile, solids whose particles are not arranged in an orderly or neat manner are usually referred to as amorphous. Amorphous solids generally have a shiny and elastic texture. Examples of amorphous solids include glass, wax, plastic, and rubber. Because the particles that are arranged in it are very closely packed together, solids cannot be compressed easily nor can they be reduced by compressing them. In solids, the individual particles do not move quickly to overcome the attractive forces between them. Which is where the particles vibrate but are tightly bound in place.



From the definition of a solid object above, it is clear that some of the properties of a solid object can be characteristic of the solid state. Following are some of the properties of objects that Sinaumed’s needs to know to recognize solid objects:  

1. Fixed Shape

The most visible property of solids is their shape which always remains under certain conditions, either in its container or in an open space. The shape of a fixed solid is influenced by the density of the molecules it contains so that it can survive under certain conditions to maintain its fixed shape. The solid form also requires a certain way or process to change it. 

This means that it is difficult for solid objects to change naturally for certain solid materials, such as plastic, wood, iron, metal, and so on. To change it, you need heat or heat energy to change its shape or form. But there are also easy solid objects that change easily like ice cubes.  

2. Fixed Volume

Apart from having a fixed shape, solids also have a fixed volume. This is influenced by the fixed shape so that the mass tends to be the same, so that the volume of solid objects does not change easily under certain conditions. The volume of a solid will remain the same if it is transferred from one container to another. To change the volume of a solid object requires a method and process of changing its shape or form in order to reduce or increase its volume. The result of changing into a solid object will also determine the volume of a fixed object. 

3. Can be Changed in Certain Ways

Just like the nature of other objects, solid objects can also experience changes in form and other forms, namely liquid or gas objects. Even though their shape and volume tend to remain the same, solid objects can change shape and form in certain ways. Such as melting and sublimation which can change the shape and form of solid objects with several symptoms, namely changes in color and smell.

Changing solid objects can undergo different processes or methods, so that it requires time and certain tools. For example, to turn wood into paper, chairs, cabinets, tables, and so on requires time and a certain way. However, there are changes in solid objects that can change easily, for example melting ice cubes or placing camphor in an open room, then these solid objects will change over time. 

4. Has Mass

Every shape or form of an object must have mass, including solid objects which also have mass properties. This mass will then affect various symptoms of these solid objects in our daily lives. For example, when there is a change in the shape or shape of a solid object, the mass of the object will change. Sinaumed’s can prove that solid objects have mass if they carry or hold solid objects, some are light and some are heavy. 

If Sinaumed’s feels this, it means that the solid object has mass. The mass of solid objects is usually measured in grams, kilograms, and so on, such as stone, wood, metal, iron, soil, sand, and so on. 

5. Incompressible

There are some solids that are incompressible. This means that solid objects are difficult to press because they have density or molecular density. Some solids don’t have voids that make them difficult to compress, such as stone, metal, wood, or plastic. Although there are solid objects that are softer, many solid objects have hard properties and are difficult to compress or compress. So it’s only natural that solid objects have a fixed shape and volume because of the nature of objects which are also difficult to compress. 

6. Can not flow

Solids don’t flow like liquids can. That means solid objects also don’t propagate easily. Solids cannot flow because they have a fixed shape and volume. This can affect the process of flow because flowing is a process that changes the shape and volume of an object, that is, it tends to follow its container like water or other liquids. 


Based on the properties of the solid objects above, Sinaumed’s can recognize them from the characteristics of solid objects that may be encountered in everyday life. The following is a summary of the characteristics of solid objects that Sinaumed’s needs to know: 

  1. The shape of solid objects will not change even if they are moved from one container to another
  2. The size of solid objects will not change even if they are moved from one container to another
  3. The volume remains under certain conditions consistently
  4. Density or density of solid objects is relatively high 


As with the shape of other objects, the shape of solid objects can also experience changes even though the shape or volume is always the same. Changes in solid objects can be in the form of changes in shape and form which can be followed by changes in color and smell of these solid objects. So a change in shape and form will definitely be followed by a change in color and smell of the solid object. 

Changes in the state of solid objects can also occur naturally or physical and chemical changes. We can recognize changes in solid objects from the process of change, such as melting, sublimation, or freezing which requires energy or heat in the process of change. The following is an explanation of changes in solid objects along with examples of changes that we often encounter in everyday life: 

1. Changes in Form

Deformation is the change of a solid object into another solid object with a different shape. Changing the shape of a solid object into another solid object still requires a special way to change it and will change the molecular structure of the solid object as well. So changes in shape in solid objects can occur through physical changes as well as chemical changes that can replace the chemical elements present in these solid objects. 

Changes in the shape of solid objects chemically cannot restore the original shape of the solid before the change occurs. The following are examples of solid objects that change shape: 

  • Plastics are included in solids because they have a high density or molecular density and are flexible, slightly strong, and slippery. If the plastic undergoes a heating process, this object can turn into various forms of objects, such as buckets, basins, chairs, tables, cabinets, plates, glasses, and various other plastic material objects. Plastic material is considered to be a material that is easy to find and the price is cheap, which is why we can easily find solid objects made of plastic. In this form change there is no chemical change because the chemical elements in the plastic are still the same, but only the shape is different, that is, some are added and some are reduced.
  • Paper is included in the form of solid objects which are the result of changes in solid objects, namely wood which is cooked into pulp or pulp. The paper material will then undergo several screening processes to form paper that we can use for writing.

2. Changes in Form

A change in state is a change in a solid object which is not only a different shape but also a change in shape. The change in form is how an object changes from a solid state to another form, namely liquid or gas. Changes in the form of liquid objects can undergo a process of physical changes that can be returned to their original form or chemical changes that occur in chemical elements, so that they cannot be returned to their original form. 

The following are examples of solid objects that undergo a change of form that Sinaumed’s needs to know about: 

  • Ice Cubes are solid objects which then have the properties of fast changing objects. This object has a fixed density and size under certain conditions, but if it is exposed to energy or heat it will change very easily. Sinaumed’s was able to observe the change in the form of ice cubes into a liquid form with a process of change, namely melting if left alone at room temperature which contains heat energy. The ice cubes will change form into water which has different properties from the previous solid objects, namely liquid objects that will follow the shape of the container and do not have a fixed mass and volume. Even so, the change of ice cubes into water is a physical change, it doesn’t experience a chemical change because it doesn’t change its chemical elements, it only changes its form.
  • Margarine is included in solids even though it has a softer shape. If this object undergoes a heating process it will change its form to become more liquid. Margarine that has been liquefied undergoes a change in form but does not experience a change in its chemical elements, so it is included in a physical change. The elements that make up the solid are still the same when they change form to liquid. 
  • Mothballs are included in solid objects that can experience a change in form if Sinaumed’s is placed in an open space, the longer it will run out. The camphor does not disappear but changes form from a solid to a gas because it sublimes into the air. This can happen because of changes in pressure, and air temperature which can make the form of camphor change. The solid properties of mothballs will also turn into gaseous objects which will follow the shape of the container or the influence of the air in a certain room. The changes that occur in camphor are chemical changes due to changes in the chemical elements of camphor which mix with air to become gas.


Looking at the changes in the objects above, Sinaumed’s can definitely find many examples of objects in the surrounding environment. We even find it difficult to escape from solid objects to fulfill our daily life, whether in the form of tools, food, and so on. The following are examples of solid objects that Sinaumed’s can find in everyday life, both natural solids or those that have changed in shape and form: 

  1. The shape of the tiles used for the roof of the house
  2. Bricks for building walls of houses or buildings
  3. Mattress from a collection of cotton or foam that is usually used for beds 
  4. Broom-shaped material used to clean the room
  5. Tables made of wood, cement or ceramic materials used to place various things
  6. A cupboard of wood or metal used to store clothes or certain objects
  7. A pot of aluminum or metal used to boil water or a utensil for cooking
  8. Stoves of iron or metal used for cooking
  9. Glass, aluminum, or ceramic cups used for drinking
  10. Dishes of glass, ceramic, iron or aluminum used for food
  11. Natural stone that is in the river or can turn into sand
  12. Wood that can be turned into various kinds of solid objects or building materials that are sturdy and strong
  13. Metal that can be made into many solid materials such as spoons, forks, plaques, and other solid objects. 

Well, that’s an explanation of the nature of solid objects starting from the understanding, characteristics, forms of change, and examples of solid objects that exist around our environment. Can Sinaumed’s understand the concept of the properties of solids? Besides being able to master physics lessons at school, understanding the properties of solid objects can also be useful in surrounding life. Sinaumed’s can maximize the understanding of the properties of solids to meet the needs of daily activities.
