Paragraph for Question Nos. 15 and 16
One mole of an ideal diatomic gas is contained in the lower part of the cylinder beneath a piston of area 50 c m 2 as shown in the figure. The piston has negligible mass but a block of mass M = 100 k g is kept on the piston. Initially the gas is maintained at a temperature of 300 K and piston is at a height h from the bottom of the cylinder. The gas is now heated to raise the weight by 10 c m . [Take g = 10 m ∕ s 2 , atmospheric pressure = 10 5 N ∕ m 2 ]
