What Are The Examples Of Physical Changes?
What did you know about the examples of physical changes? Nothing? Don’t worry, we are here to help you out. In this article, we will provide you with all possible examples of physical changes in detail. There are two main components in the physical changes and they are matter and energy. You must know that no new substance is created during the physical changes, although the matter takes a different form. The size, color, shape, or matter may change, but matter does not change. Physical changes occur when the substances are mixed but do not chemically react. Well, have a look at the examples of physical changes.
What Is Physical Change?
A physical change is opposite to a chemical change and it only affects the physical properties of the substance. The physical properties of substances include shape, size, color, texture, mass, and density. These changes are not to be confused with chemical changes, which form whole new substances.
Physical changes are reversible but not all physical changes are reversible. For example, if you freeze water into an ice cube, you can melt it into the water again. But, if you heat the raw egg to cook it, then you can convert it into its original form by cooling it. It is an irreversible type of physical change. The most essential point you should remember is that, in physical changes the appearance of matter changes, but its chemical identity remains the same.
Let’s know the physical changes of matter examples in detail.
What Are The Examples Of Physical Changes?
Here is a list of some prominent examples of physical changes,
- Boiling
- Cutting
- Blending
- DIssolving
- Melting
- Freezing
- Breaking A Glass
- Shredding Paper
- Mixing Sand And Water
9 Examples Of Physical Changes
There are more than 20 examples of physical changes but here we will give you some important and common examples. Let’s understand them,
1. Boiling
Boiling is one of the common examples of physical changes in chemistry. During boiling, water changes from liquid to a gaseous state. And you can again convert it into the water by compressing the vapors. So, you found there is no change in the original substance.
2. Cutting
One of the great examples among many examples of physical changes of matter is cutting. In the cutting of a stone, no new substance is formed as the stone is cut into two or more pieces only the size, and shape of the stone change. It is an irreversible physical change as you can not reverse pieces into stone.
3. Blending
Blending is one of the good examples of physical changes in our daily life. Blending smoothies involves two physical changes, one is the change in the shape of each fruit and the second is the mixing together of many different pieces of fruit. But its yielding is different from the original fruit. So, it is an irreversible physical change.
4. Dissolving
Examples of physical change in the kitchen include dissolving. For example, when you dissolve a spoonful of sugar in a glass of water, the sugar particles spread out and form a solution with water. This process can be reversed by evaporating water and collecting the sugar.
5. Melting
Examples of physical changes in cooking include melting. For example, if you melt a piece of butter after cooling you can again convert it into butter or solid. Melted butter and solid butter have the same chemical properties. But, when you melt the sugar, it turns into a brown substance. You can not convert it back into white sugar but it has the same composition as white sugar. It is an irreversible physical change.
6. Freezing
One of the simple yet common examples of physical changes in science is freezing. Freezing can naturally happen in the winter season in some regions of the earth. Also, freezing is one of the common examples of physical changes at home. When you freeze water in the refrigerator into ice cubes, you can convert it back into the water again.
7. Breaking A Glass
When you break the glass into multiple pieces, you will find no chemical change in the glass. Only its shape and size changed. Therefore, it is also a physical change.
8. Shredding Paper
Shredding paper is a physical change because the composition of the paper is not changed. Only the physical appearance of the paper is changed. For example, crushing a piece of paper.
9. Mixing Sand And Water
When you mix a feastful of sand into a glass of water, then you will find that there is no change in the chemical composition of both substances. Also, you can easily segregate sand from water. Therefore, the mixture of sand and water is also an example of physical change.

Conclusion
After reading this article, you have caught a very common point that in the physical change the chemical composition of the substance remains the same. No new substance is formed in the physical changes. The best thing about physical changes is that you can see the change happening in the substance with your naked eyes. Because in this type of change the properties of substances like color, shape, size, etc get changed. Now, you have understood everything about the examples of physical changes.
