So this question is looking at the behavior of gas molecules and at some statements about them, and if they are false, we need to correct them, and if they're true, or we can just go on.
00:14
So statement a, at constant temperature, the lighter, the gas molecules, the faster the average philosophy of the gas molecules.
00:20
This is true.
00:23
The idea of temperatures related to kinetic energy, and a lighter particle has to be moving faster to exert the same connect.
00:31
Energy as a heavier particle.
00:34
B, at constant temperature, the heavier the gas molecules, the larger the average kinetic energy.
00:40
That is false.
00:42
So the statement here should be that at constant temperature, the heavier the gas molecules of the slower, the average velocity.
01:04
The slower particle can exert the same force as a faster particle, as a lighter particle.
01:15
For c, a real gas behaves most ideally when the container volume is relatively large, and the gas molecules are moving relatively quickly.
01:24
So this is false.
01:27
The second part is true.
01:29
It does need to be moving quickly, so it needs to have a very high temperature, but it also needs to be low pressure.
01:37
So it's to say low pressure and high temperature...
