EVAPORATION:
1. IT IS A SURFACE PHENOMENA
2. IT DOESNT NEED BOILING POINT TO BE REACHED
3. IT IS A SLOW PROCESS.
4. EXAMPLE. DRYING IF CLOTHES
BOILING:
1. IT IS A BULK PHENOMENA
2. IT NEEDS BOILING POINT TO BE REACHED
3. IT IS A RAPID PROCESS.
4. EXAMPLE. BOILING OF WATER

Evaporation:
1) Evaporation occurs on the surface of the liquid and it is the vapourisation of the liquid.
2) The process is slow and can't be seen at all.
3) It is a state of transition from liquid to gas.
4) Evaporation can occur at any temperature. It occurs as long as the substance is a liquid at a particular temperature.
Boiling:
1) Boiling occurs on the entire mass of the liquid and is also the vapourisation of the liquid.
2) The process occurs rapidly.
3) It is a state of phase transition.
4) Boiling occurs when the temperature of the liquid is greater than the boiling point of the substance.
