How does temperature affect the evaporation of water?

Answer 1

Liquid does not need to be heated to evaporate. This should not be confused with boiling when heat is certinly required.

In a liquid, all the particles have a range of energies; some are stationary and some are moving very quickly. This quicker ones may have enough energy to overcome the energy holding them in the liquid (intermolecular forces such as Van der Waals). When these higher energy molecules leave, the lower energy molecules still remain and so the average energy of the molecules decreases. This registers as a drop in temperature.

When you get Acetone (nail varnish remover) on your hand, you should be able to feel this effect. It is also what causes you to feel cold after leaving a swiming pool on a hot day.

ANSWER

The physical states of matter depend on the amount of energy holding the matter in a certain state versus the amount of energy in the substance that makes the molecules try to escape (and evaporate). Basically, energy is required for evaporation to take place. This is why evaporation causes the cool feeling on your body as you dry off. The water just takes energy (heat) from your body to help push the molecule out of liquid solution. Remember that pressure (generally from the atmosphere) is what holds a liquid in the liquid state. If you remove the pressure of the atmosphere from just about any liquid, it will vaporize whether more energy is added to the liquid or not. Unless the liquid is already at nearly absolute zero, it will have enough heat energy to evaporate in the absence of air pressure holding it in the liquid state. A quick, one sentence answer to this question: Evaporation will COOL the liquid off. Evaporation will cause heat energy to be removed from somewhere (generally the liquid from where the molecule evaporated from).

Well, according to the question it can be concluded that when a liquid is boiling and the water molecules are gaining excess energy, eventually excited to evaporate in the atmosphere. The affects are not much because the liquid's temperature is already high to boil the liquid. Evaporation is the process when a liquid get extra energy to energize the water molecules (H20) to gain energy to change their form to gas to escape into the atmosphere. The temperature of the liquid will will cool down as the molecules escape with the extra energy to change their form to gas.

Answer 2

In liquid, some of the particles have enough kinetic energy to escape from the surface this is called evaporation. Since these high energy particles leav the liquid, the kinetic energy of the remaining molecules is reduced which means that the temp of the remaining liquid would drop.

Answer 3

higher the temperature the more the water evaporates. for example like in a sauna, when you pour the water over the scolding hot rocks it evaporates within seconds.
