Question

A vessel contains 1 mole of $	ext{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. P = nRT/V. For identical vessel, V and n are same. P is proportional to T. Since T is doubled, P is doubled. Therefore, correct answer is C.
