What temperature can a particle escape from a liquid?
Particles can evaporate from a liquid at temperature that is much lower than the liquids boiling point

What are the conditions necessary for a particle of water to evaporate from a liquid?
The particles are travelling in the right direction to escape the liquid. - The particles are travelling fast enough (they have enough kinetic energy) to overcome the attractive forces of the other particles in the liquid.

What happens to the temperature of a liquid when a particle of water evaporates?
the average speed and kinetic energy of the remaining particles decreases.5. This decrease in the average particle energy means the temperature of the remaining liquid falls-the liquid cools

Give an example when the cooling effect from evaporation is useful.
6. This cooling effect can be really useful. For example, you sweat when you exercise or get hot. As the water from the sweat on your skin evaporates, it cools you down.
