A highly conducting chamber contains air at a pressure of 75cm of Hg. The chamber is divided into two halves by a conducting piston fitted with a handle. The chamber is completely air tight. The piston by means of the

handle is slowly pulled towards right half way. The pressure difference across the piston will be:

A

100 cm of Hg

B

112.5 cm of Hg

C

125 cm of Hg

D

zero

A cylinder with a movable piston contains air under a pressure P_1 and a soap bubble of radius 'r'. The pressure P_2 to which the air should be compressed by slowly pushing the piston into the cylinder for the soap bubble to reduce its radius by half will be : x[P_1 +3S//r] , where S is the surface tension
