Physical changes involve changes in the physical properties of an object or substance. These changes can be observed directly, such as when a metal object gets hot or a piece of ice melts, or indirectly, such as when the volume of water in a glass increases when it is poured in.
Here are some examples of physical changes in everyday life:
Melting: Water turns into liquid when it is heated. This is an example of a physical change because the water's properties change.
Freezing: When water is cooled, it turns into a solid. This is also an example of a physical change because the water's properties change.
Compressing: When you press down on a balloon, it gets smaller. This is an example of a physical change because the balloon's volume changes.
Dilation: When an object is heated, it expands in size. This is an example of a physical change because the object's volume changes.
Rusting: When iron is exposed to air, it rusts. This is an example of a physical change because the iron's properties change.
These are just a few examples of the many physical changes that we encounter in everyday life. By understanding these changes, we can better understand the world around us and how it works
