Question

A vessel contains 1 mole of $O_2$ gas at a temperature T. The pressure of the gas is P. An identical vessel containing 1 mole of He gas at a temperature 2T has a pressure of

Prashant Kotian · Accepted Answer

Correct answer: C. From PV = nRT, P = nRT/V. Since V, n, and R are identical, P is directly ∝ absolute temperature. Changing the temperature from T to 2T doubles the pressure to 2P.
