A physical change is reversible and does not affect the composition of a substance.
On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
It is a physical change, the substance stay the same elements before and after the change, this is the same for all states of matter changes (melting, freezing, evaporating, condensing, and sublamation)
Physical change, as change in state.
physical
A change in temperature or pressure can affect the state of matter without altering its chemical composition. For example, melting ice to form liquid water or boiling liquid water to form steam are changes in state of matter that do not change the chemical makeup of water molecules.
A change in state of matter, such as melting, freezing, or boiling, will affect the arrangement of particles without changing the chemical composition of the substance. For example, ice melting into water involves a change in state from solid to liquid, but the chemical makeup of water remains the same (H2O).
A change in state is a physical change because the chemical composition of the substance remains the same.
Physical. The water changes its state of matter from liquid to gaseous. No chemical reaction (i.e. change) going on there.

Temperature.
A change in temperature or pressure can affect the state of matter without altering its chemical composition. For example, melting ice to form liquid water or boiling liquid water to form steam are changes in state of matter that do not change the chemical makeup of water molecules.
chemical changes affect the chemical properties as well as composition of matter , that result in the formation of a new substance.
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
No, temperature is not a chemical change. Temperature is a measure of the average kinetic energy of particles in a substance and does not involve the rearrangement of atoms or formation of new substances.
A change in state of matter, such as melting, freezing, or boiling, will affect the arrangement of particles without changing the chemical composition of the substance. For example, ice melting into water involves a change in state from solid to liquid, but the chemical makeup of water remains the same (H2O).
The different changes in matter,basically,are phsical change and chemical change. You 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.
