2. Physical change - a change from one state
(solid or liquid or gas) to another without
a change in chemical composition
Physical changes occur when objects or substances undergo a
change that does not change their chemical composition. This
contrasts with the concept of chemical change in which the
composition of a substance changes or one or more
substances combine or break up to form new substances
