Okay, so in this question, we have a piston and it's undergoing certain changes.
00:09
And they're asking us to redraw what the piston would look like after these changes have taken effect.
00:15
So in the first one, we can see that we're going from the temperature of 300 kelvin to a temperature of 450 kelvin.
00:21
So this is already in kelvin.
00:24
It's an absolute temperature, which means that we can treat it proportionally.
00:28
So if we look at this, the temperature is increasing by 50%.
00:33
Which means that the volume would also increase by 50%.
00:38
So we'd be right around here.
00:47
In the second one, the pressure is increasing from one to two.
00:52
So essentially what we're saying is we're pushing the piston down further to increase that pressure, to increase the force on that gas.
01:00
And if the pressure is doubled, that means the volume is going to be cut in half...
