Question

differentiate between evaporation and boiling give three differences for each

Answer 1

boiling :- 1.boiling is a bulk phenomenon .
2.particles attain higher kinetic energy and convert into vapours .
3.during boiling average kinetic energy increases .

evaporation :- 1.evaporation is a surface phenomena .
2.particles of a liquid are constantly moving with different kinetic energy is when particles of higher kinetic energy come to the surface the break away from the surface of the liquid and become vapours .
3.during evaporation average kinetic energy decreases .

Answer 2

Evaporation starts at a temperature which is not fixed while boiling point of a liquid is sharp and is fixed.

Evaporation is the process of conversion of water from liquid to solid states while boiling point is the point where the pressure of liquid equal to the atmospheric pressure.

Evaporation depends on surface area of the exposed part while boiling is independent of surface area.
