Does energy need to be absorbed to convert a liquid to a gas?

Yeah obviously.... Any matter in this universe tries to be more disordered state. By absorbing energy, Liquid state, in which molecules move less freely tries to be move more freely by absorbing energy and changing into gaseous state..


The changing of gaseous water vapor in the air to liquid water?

The changing of gaseous water vapor in the air to liquid water is called condensation. If it does so high up in the atmosphere and falls as droplets to the ground we call that "rain" - but it has to undergo condensation first.


What are the differences between freezing melting and evaporation?

Changing the liquid state to solid state is known as freezing, changing from solid state to liquid state is known as melting and changing from liquid or solid state to gaseous state is known as evaporation.
