Statement 1: Heat supplied to a gas is process is 100 J and work done by the gas in the same process is 120 J, then pressure of he gas in the process should increase. because Statement2: Work done by the gas is greater than the heat supplied to the gas. Hence, internal energy of the gas should decrease.
