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).
After death, the body undergoes several physical changes including rigor mortis (stiffening of muscles), livor mortis (pooling of blood in the lowest parts of the body), and decomposition (breakdown of tissues by bacteria and enzymes). These changes begin immediately after death and progress over time, leading to the eventual decay of the body.
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
because atoms expands when temperature increases in result physical changes.

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.

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.
Mostly chemical, but physical changes also occur, such as when the windows blow out.
