I'm blurring the names out, so my teacher doesn't get doxed, and so I don't get doxed either
Guys I learned something about gas properties/molecules yesterday. The more pressure there is, the faster the particles go. (Heavy or Light.) The less pressure, the slower they go. (Heavy or Light.) The heavier molecules go slower but bounce off of each other on contact, and the Light ones still bounce on contact but (base) speed is higher than Heavy molecules.
