Hello.
00:01
Today we'll be talking about chapter 12, question 9, which tells us about a sample of helium.
00:07
Let's say it's in a balloon that we have.
00:10
And that helium has a volume of 240 milliliters.
00:16
We have a tiny balloon, 240 milliliters of helium gas.
00:21
And so the pressure inside this balloon, this tiny little balloon, is 0 .428 atmospheres.
00:30
So this balloon is probably not inflated very much at all, but i've drawn it as though it is.
00:36
And we increase the pressure.
00:38
Perhaps we put the balloon in a hydraulic press.
00:42
It's a very sturdy balloon...
