a) Factors

When liquid particles evaporate, they create a vapour above the liquid. Particles escape from the liquid to the vapour but also return from the vapour to the liquid. When the temperature is below the boiling point of the liquid, the number of liquid particles escaping from the liquid is equal to the number of particles returning to the liquid, unless certain factors affect the equilibrium.

i) Particle Mass & Attraction

For a particle to escape from the liquid, it must have more energy than...
