The pressure decreases.

#### Work Step by Step

A decrease in temperature decreases the pressure of a contained gas. You could also refer to Gay-Lussac's Law which states that the pressure of a gas is proportional to its temperature (in Kelvin), assuming that its volume doesn't change. As temperature increases, pressure increases; and as temperature decreases, pressure decreases.
