Reduction of temperature?

Explanation:

#P.V = nRT#

P is pressure, V volume, n amount of substance, R is gas constnat and T temperature.

Amount of substance is constant, the gas constant R is obviously a constant, and it's a closed container so volume V is also constant.

So with V, n and R all being constant, P is proportional to T. In other words, reduce temperature = reduce pressure.
