A vertical hollow cylinder of height 1.5...

A vertical hollow cylinder of height 1.52 m is fitted with a movable piston of negligible mass and thickness. The lower half portion of the cylinder contains an ideal gas and the upper half is filled with mercury. The cylinder is initially at 300 K. When the temperature is raised, half of the mercury comes out of the cylinder. Find this temperature, assuming the thermal ·expansion of mercury to be negligible.

A

137.5 K

B

237.5 K

C

337.5 K
