Why Does Water Evaporate At Room Temperature

There is not a specific temperature that water must be in order for it to evaporate.

Why does water evaporate at room temperature. The faster they move the more likely it is that they will break away from the pack and evaporate. What is evaporation. Clearly water does evaporate at 212ºf but it also evaporates at room temperature. The average energy can be low and the evaporation still continues.

So depending on the temperature outside it may evaporate faster or slower than inside at higher temperatures water will evaporate faster. All fluids are always evaporating. Energy is used to break the bonds that hold water molecules together which is why water easily evaporates at the boiling point 212 f 100 c but evaporates much more slowly at the freezing point. However as temperature rises evaporation typically increases because water molecules are moving more quickly.

Some have low velocities while some have very high velocities. Evaporation is all about the energy in individual molecules not about the average energy of a system. When a lot of water vapor is in the air molecules will get bumped up against a surface and stick to it which is why condensation forms on the outside of a cold drink on a humid day. At higher temperatures water will evaporate faster.

Olive oil in contrast has a very low vapor pressure so it s not likely to evaporate much at room temperature source. It turns out that all liquids can evaporate at room temperature and normal air pressure. You might be wondering how that can happen when the temperature is low. Most molecules have a most probable velocity which is low for water at room temperature.

A fluid has billions of molecules all whizzing around at different speeds. High temperatures just increase the rate of evaporation.
