This question is asking for a description on the critical.
00:07
Now we have to appreciate that this critical point is a point, so it is a combination of the critical temperature and the critical pressure.
00:19
So what we mean by the critical temperature? this is the temperature beyond which you cannot distinguish between a gas and a vapor phase.
00:32
So above the critical temperature, so it is that temperature beyond which you cannot liquefy acres.
00:43
So if you increase the temperature of a substance beyond the critical temperature, you cannot liquefy it by simply changing its pressure.
00:52
So looking at the critical pressure, the corresponding critical pressure, this is the pressure, the critical pressure, this is the pressure, this is the pressure.
01:05
Required to liquefy a gas at critical temperature.
01:20
So if you've got a gas, if you've got a gas, that is a critical temperature...
