A horizontal piston cylinder arrangement encloses a gas at a

A horizontal piston cylinder arrangement encloses a gas at a pressure Po The atmospheric pressure is also Po Now a particle of mass m strikes the piston of identical mass m with a horizontal speed u and sticks to it Subsequently the piston moves without friction and compresses the gas The process of compression can be assumed to be adiabatic In this Po m process A when the piston comes to rest at maximum compression the internal energy of gas would 1 have increased by mu 4 B During the time interval starting from the mass striking the piston to the maximum compression of the enclosed gas the work done by the gas is mu When the piston comes to rest after compressing the gas the internal energy of the gas would have increased by the amount more than mu 4 D During the compression of the gas till the time when piston comes to rest work done by the gas is less than mu 4
