A graph drawn between absolute temperature and volume of 3 moles of helium gas as shown in the figure. If 5 cal of heat is used in the process, then the work done is

Two moles of helium gas are taken along the path ABCD (as shown in Fig.) The work done by the gas is

Two moles of helium gas are taken along the path ABCD (as shown in Fig.) The work done by the gas is

Two moles of helium gas are taken along the path ABCD (as shown in Fig.) The work done by the gas is

the volume( V) of a polyatomic( non linear molecule) gas varies with its temperature(T) , as shown in figure. The ratio of the heat absorbed by the gas to the work done by the gas, when gas is taken from state A to state B , is ( neglect vibrational mode)

Two moles of helium gas undergo a cyclic process as shown in figure. Assuming the gas to be ideal. The net work done by the gas is
