Eli5: Does hotter temperatures evaporate water faster when cooking?

488 viewsChemistryOther

If I put a cup of water in an oven proof container and boil it in an oven at 400 degrees, and then do it with an oven at 500 degrees,

Will the hotter oven evaporate the water faster?

My thought is it will all evaporate at 212 but the hotter oven would make it to 212 faster. Aside from that, would a hotter temp make it happen faster if all other things were equal?

Assuming standard pressure, water can evaporate at room temperature, this is because of a thing called vapor pressure.

Vapor pressure is the tendency for a liquid to turn into a gas. Basically any liquid with heat (i.e. anything above absolute zero), the molecules of the liquid will be moving; the more heat, the faster the movement. The more movement, the more likely it is that an individual molecule will be able to break away from the rest. This breaking away is evaporation.

So, it would stand to reason that the more heat applied when cooking will cause the water molecules to move faster, and thus evaporate sooner.
