Hey Chad, towards the end when talking about melting CO2 you said we would have to increase the pressure. I'm a little confused because if we're in the solid phase, and we want to melt it by going into the liquid phase, don't we have to move right on the diagram which would be increasing the temperature? Thanks!

hey, is there reason why there is no chapter 12 in this series? thanks!!

[@ChadsPrep]

There is a chapter on modern materials that is not normally covered and I haven't made any videos for it. But I saved room for it as I feel it would be a good chapter to include in a complete set of lectures on general chemistry. No ETA on it at this point.

Pretty sure the thing about pressure causing the slipperyness of ice is a myth. People aren't heavy enough to make the ice melt even with skates on, and ice remains slippery quite a lot below freezing temperature, so while it makes sense in principle it does not work out mathematically.

I will look into this further as I've been propagating this myth for well over a decade (yikes)! 😲😲😲 Loving the critique you're providing in your comments. I'm guessing there's a good chance you teach?
