Solution: Pressure and temperature are directly proportional. We know this from the ideal gas law PV=nRT. If two terms (such as P and V) are on the same side, they are inversely proportional. If two terms are on opposite sides such as P and T, they are directly proportional. Directly proportional means that as the temperature increases, pressure increases as well.
