See isobaric (constant pressure) process for a gas.

[itex]PV = nRT[/itex]

If pressure and composition are constant

[itex]\frac{P}{nR}V = \kappa V = T[/itex]

This is Charles law.

As stated in the above equation, the temperature of a set number of molecules can increase while the pressure remains constant, just so long as the volume of the molecules increases. Or you can say just the opposite, the the temperature of a set number of molecules can decrease while the pressure remains constant, just so long as the volume decreases.
