6: 28 Critical pressure is NOT the pressure at which a substance remains a liquid regardless of temperature. There is no such pressure, as we can always exceed the critical temperature and create either a gas or supercritical fluid. Critical pressure is the pressure at which a substance remains liquid at the critical temperature. The (x, y) coordinates of the critical point are (critical temperature, critical pressure)

probably good information, but she speaks so fast with never a pause for comprehension, that this video is rather useless to me. Its like they are trying to win a prize for -How much information can you compress into the shortest possible time-. You have to be a special kind of hyper-active to go at this pace.
Other sources have the same content but are more useful for normal learning.

I absolutely agree, a math series with the ease and casualness of Crash Course, would be monumentally beneficial for a lot of students across the world. Starting at Algebra 1 and Geometry (for an intermediate Mathematics Series) Algebra 2- Trigonometry- Calculus AB - Calculus BC- Statistics ( for an advanced Mathematics Series)

This video was very cool. I think the strangest part was that the interactions of a gas at varying pressure or temperature was considered 'strange'. It makes sense when you think of the gas's polarity and subsequent interactions with other atoms

One thing that struck me earlier, though it is more a chemistry thought.
Does a single atom have a state? Can it be a liquid, a gas, or a solid, without other atoms of its kind to interact with?

I've watched very single crash course video for fun and i am in grade 4 standard 2 and i'm the smartest in my school I've moved up 2 grades! watch these people!
