Changes

: When a [[gas]] is not in a container or the container can change size then when the [[temperature]] increases and causes a [[pressure]] increase the [[gas]] will increase in [[Volume (Space)|volume]].

: Increasing the [[Volume (Space)|volume]] of a [[gas]] at constant [[temperature]] will decrease the [[pressure]] on the walls of the container because it takes the [[particle]]s longer to move from one side of the container to the other. This means there will be less frequent [[collision]]s of the [[particle]]s with the walls.
