Yes there must be achange;but heat is required to change liquid state into gaseous state.
During a physical change, the composition of matter remains the same. The atoms and molecules of the substance do not change; only the arrangement or state of the matter is altered. This means that no new substances are formed during a physical change.
At first it was a solid now it is a liquid

state of matter
state of matter: the mix is turning from a liquid to a solid.
During vaporization, matter changes from a liquid state to a gaseous state without undergoing a chemical change. The phase change involves the absorption of heat energy to overcome intermolecular forces holding the molecules together in the liquid form.
Phase change
evaporation.
1. A change of the phase of matter: liquid to solid, gas to liquid, solid to liquid. 1. Absorption or release of energy.
During the melting the structure of the material is destroyed and the liquid is a low oredered state of matter.
Heating can change matter from a solid to a liquid or from a liquid to a gas. Cooling can change matter from a gas to a liquid or from a liquid to a solid.
the matter can change into liquid, solid and gas.
