JEE Advanced 2020 Full Test 1 Paper 2

This section contains 02 paragraph each describing theory, experiment, data etc. Four questions relate to the paragraph. Each question of a paragraph has Only One correct answer among the four choices (A),(B),(C) and (D). One mole of an ideal diatomic gas is contained in the lower part of the cylinder beneath a piston of area 50cm2 as shown in the figure. The piston has negligible mass but a block of mass M=100kg is kept on the piston. Initially the gas is maintained at a temperature of 300K and piston is at a height h from the bottom of the cylinder. The gas is now heated to raise the weight by 10cm. [Take g=10m∕s2, atmospheric pressure =105N∕m2]
