Two bulbs of identical volumes connected by a small capillary are initially filled with an ideal gas at
temperature T. Bulb 2 is heated to maintain a temperature 2T while bulb 1 remains at temperature T. Assume
throughout that the heat conduction by the capillary is negligible. Then the ratio of final mass of the gas in
bulb 2 to the initial mass of the gas in the same bulb is close to -
(A) 1/2 (B) 2/3 (C) 1/3 (D) 1
