When a liquid evaporates or changes to a gas, it is referred to as a vapor.
00:12
So evaporating to go from a liquid to a gas means it is vaporizing.
00:19
And vapor pressure refers to the pressure of a vapor, in other words, it's a gas, above its liquid.
00:41
So therefore, since pressure results from the collision of gas particles with their container as the number of vapor particles increases, the vapor pressure will increase.
01:17
Okay, so let's look at what we have here so far.
01:20
We have, say we have a container with a liquid in it.
01:28
So we have a liquid in this container.
01:34
And at any temperature, some of that liquid is going to vaporize.
01:41
Let's say we put a stopper on this container also.
01:44
So the vapor that is produced is going to be trapped in there.
01:50
All right.
01:51
Well, the more vapor we have, so the pressure from this vapor is going to be caused by the collisions with the walls of their container.
01:58
But if we have more vapor, there's going to be more collisions and an increase in vapor pressure.
02:04
So that's what we're talking about here when we said as the number of particles increase, the vapor pressure will increase...
