I'm a bit confused...for G.Chem (gases) it says that gases expand when heated and contract when cooled, which makes sense b/c as T increases so does V at constant pressure.
However, then in the thermodynamics section where it talks about E=q+w, it also says that as gases expand they cool and that compressing gases warm up. I'm really confused about this..can someone help me out..thanks!!
