when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
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.
With the help of some physical and chemical processes matter changes its state. Like using heating , cooling etc we can change the state of matter,
Changes of state of matter are physical processes, the molecule remain unchanged.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.

Matter changes state because of pressure and temperature.
how temperature can bring about changes in the state of matter

Matter changes state because of temperature and pressure. These quantities bring change.
Changes of state of matter are physical processes, the molecule remain unchanged.
Molecules can change states of matter through the processes of melting, freezing, vaporization, condensation, and sublimation. These changes in state occur when the temperature or pressure of the substance is altered, causing the molecules to rearrange in a way that transitions the substance from one state to another.

Chemistry
The particle model of matter describes matter as being made up of tiny particles (atoms and molecules) that are in constant motion. Changes in temperature or pressure affect the motion of these particles. With an increase in temperature, the particles move faster, leading to a change in state (e.g., solid to liquid to gas). Changes in pressure can also affect the arrangement and movement of particles, causing changes in state.
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.
