Okay, so this question is asking us why the heat of fusion of a substance is smaller than its heat of vaporization.
00:07
So first off, let's just, you know, kind of define what heat of fusion is.
00:12
And so heat of fusion is basically the heat absorbed by, you know, any certain amount of a unit of mass or the amount of energy that is needed to melt or freeze a substance.
00:26
While the heat of vaporization, on the other hand, is the heat that is absorbed when a liquid actually vaporizes.
00:36
The changing of a, you know, the amount of heat that is needed to turn a liquid into its gaseous form, into a vapor.
00:45
And so what we need to do here is kind of think about what is happening when these things are going on.
00:51
So fusion, like i said, is the process of changing it, or is the energy needed to melt or freeze a substance.
01:06
So this is, you know, melting and freezing.
01:09
That's dealing with, you know, freezing is, you know, liquid to solid, and melting is, you know, the opposite...
