360Science™: Relationships Between Gas Variables


Students follow a detailed procedure to observe either a) that there is an inverse relationship between the pressure a gas exerts and the volume of the container in which it is held; or b) that there is a direct relationship between the temperature of a gas and the volume it expands to fill. Students share data if time does not allow them to complete the entire procedure.
