Question

A container contains certain gas of mass $m$ at high pressure. Some of the gas has been allowed to escape from the container. After some time, the pressure of the gas becomes half and its absolute temperature two-third. The amount of the gas escaped is

Prashant Kotian · Accepted Answer

Correct answer: C. m2/m1 = (P2/P1) * (T1/T2) = (1/2) * (3/2) = 3/4. Mass escaped = m - 3m/4 = m/4. Therefore, correct answer is C.
