In both cases below, one mole of an ideal gas is expanded from an initial volume V to a final volume 2 V. In both cases, the gas is identical and the initial pressure is 2P. The expansion is adiabatic in A and isothermal in B. Will the final temperature of the gas be (i) greater in Case A, (ii) greater in Case B, or (iii) the same in both cases? Explain your reasoning
