In this question, we're asked, water can be cooled in hot climates by evaporation of water from surface of canvas vets.
00:09
What mass of water can be cooled from 35 to 30 degrees celsius through evaporation of one gram of water? so first of all, let's figure out the energy that would be released, or the energy that we would need to evaporate one gram of water.
00:29
So we'll convert grams to moles, and then we're going to use qipa's and delta age vaporization.
00:36
So if you use the value of heat of vaporization in joules per gram, then we do not have to convert to moles, but there just depends on what units are on your heat of vaporization.
00:52
Just be sure it matches the unit on moles or grams of water.
00:57
So we are going to have those cancel.
00:59
We have the energy that would be required.
01:02
Then use qikos mc delta t...
