Gas Law Problems: We have a problem with the gas molecule. Why is this a problem? 1) They show attraction! Cant in Gas Law Problems 1) They take up space!!! Cant in Gas Law Problems Its our Physics problem: Disregard air resistance How do you do that?
Real Gases 1) They do exist. 2) They can liquefy - condensation of vapor. 3) They dont follow gas laws.
Ideal Gases 1) They dont exist. 2) They cant liquiefy. 3) They follow the gas laws.
So when do gases behave ideally so we can use them in our gas laws? Where they show no attraction to each other: What conditions would that be?
