Gas
actually solids will be the best answer for this
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
Physical changeschemical changesYou must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
Matter can undergo physical changes, such as changes in state (solid, liquid, gas) or shape, without altering its chemical composition. It can also go through chemical changes, resulting in new substances with different properties due to rearrangement of atoms or breaking of chemical bonds. Additionally, matter can experience nuclear changes, like radioactive decay, where the nucleus of an atom changes leading to the formation of different elements.
Gas
Gases adapt most easily to changes in volume.

When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
Ice melting into water is an example of matter undergoing a physical change. The ice changes from a solid state to a liquid state without altering its chemical composition.
Energy.
Characteristics like temperature, pressure, and state (solid, liquid, gas) can affect physical changes in matter. Additionally, factors like size and shape of the particles can influence how matter responds to external conditions and undergoes physical changes.
It is called "melting". It means that when a solid gets so hot, by the increase in Kinetic Energy that it contains, the atoms move around so much that the state of matter changes to a liquid, that is to say it undergoes a change of state. Further heating will change the liquid to a gas - another change of state.
