00:01
So we can actually say that which factors would actually contribute to this phenomenon.
00:10
We have same freezing and boiling points, but now a boils before b.
00:23
And so we can say that for part a, rather for option a, is saying that b the specific heat of b is greater than the specific heat of a.
00:37
This would mean that it requires more joules or more thermal energy in order to raise the temperature of b of substance b.
00:49
So this would actually explain why a would boil before b.
00:55
For option b, we have substance b has a larger latent heat of vaporization.
01:04
So we can say the latent heat of vaporization for b is greater than the latent heat of vaporization for a.
01:11
This would also explain the phenomenon given that the latent heat of vaporization is simply the energy required to actually boil this substance or turn it from a liquid to a gas.
01:26
And so we would have to, of course, raise it to the boiling temperature and then additionally add a certain amount of energy to actually boil and actually make the phase change.
01:43
So the temperature change is one part.
01:46
The phase change is another part of the physical process.
01:53
And so this would explain the phenomenon.
01:57
C, we have the latent heat of fusion of b greater than the latent heat of fusion of a...
