Eli5: Does hotter temperatures evaporate water faster when cooking?

587 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?

Heat transfer is proportional to the difference in temperature. The water will be 212 degrees and receiving heat from the hotter air around it. Each unit of heat evaporates a certain amount of water. If we assume the oven is able to maintain the air at the set temperature, then 500 degrees will transfer heat into the water about 50% faster, and thus boil away the water about 50% faster.
