because atoms expands when temperature increases in result physical changes.
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).

The most common physical changes that occur include changes in muscle mass, bone density, skin elasticity, and metabolism. Additionally, changes in vision, hearing, and hormone levels are also commonly experienced with aging.

Physical change as it is only changing its physical apparence, not the content of the object
Mostly chemical, but physical changes also occur, such as when the windows blow out.
The process of bees converting nectar into beeswax and then into honey involves both chemical and physical changes. Chemical changes occur during the conversion of nectar into beeswax and honey, while physical changes occur during the shaping, cooling, and solidification of the wax.
