If heat is transferred away from gaswhat could happen?

In order to understand this problem, you need to understand the equation PV = nRT. P meaning pressure, V meaning volume, n meaning number of moles, R meaning the ideal gas constant, and T meaning temperature. Since the number of moles and the gas constant are not changing, the temperature will cause the pressure and volume of the gas to increase as it itself increases. Likewise, as the temperature decreases the pressure and volume of the gas will decrease.
