Yes there must be achange;but heat is required to change liquid state into gaseous state.
If you mean the "state" of matter, during evaporation, it changes from a liquid to a gas.
At first it was a solid now it is a liquid
At first it was a solid now it is a liquid
When a matter changes from a gas to a liquid it is called condensation.
state of matter
state of matter: the mix is turning from a liquid to a solid.
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.
evaporation.
the matter can change into liquid, solid and gas.
Because melting is a change of state: from solid to liquid.
