If the temperature of a gas at constant volume doubles, what happens to its pressure?

Explanation:
For an ideal gas, with volume and amount of gas fixed, pressure is directly proportional to temperature (P ∝ T from PV = nRT). So if you double the temperature (in Kelvin), the pressure doubles as well. The Kelvin scale matters here because the relationship uses absolute temperature. Therefore the pressure doubles.
