Question: A 2.25 mol sample of an ideal monatomic gas undergoes the reversible process. The scale of the vertical axis is set by Ts = 457 K and the scale of the horizontal axis is set by Ss = 25.6 J/K.
Part A: How much energy is absorbed as heat by the gas?
Part B: What is the change in the internal energy of the gas?
Part C: How much work is done by the gas?
Please show all work and steps to determine the change in the internal energy of the gas.
