Okay, so now we're working out problem number 56.
00:06
Why is the heated vaporization of water greater at room temperature than it is at its boiling point? and the idea behind this is pretty simple.
00:18
So when you're at room temperature, you have molecules and atoms slamming around at very slow speeds relative to boiling point.
00:36
And you can imagine what happens.
00:38
If this is water with pretty strong intermolecular forces because there are hydrogen bonds of keeping molecules of water together, then the slow motion won't contribute much, and it won't help when you're adding heat to the system very much in order to eject molecules of water from the surface.
01:08
So let's pretend this is with this surface.
01:10
In here so that you have atoms or molecules leaving the surface.
01:19
Okay, so if i raise the temperature to the boiling point, then i'll have much, much faster molecules...
