In the figure an ideal gas changes is state from state A to state C by two paths ABC and AC.
(a) Find the path along which the work done is least.
(b) The internal energy of the gas at A is 10 J and the amount of heat supplied to change its state to C through the path AC is 200 J. Calculate the internal energy at C.
(c) The internal energy of the gas at state B is 20 J. Fid the amount of the heat supplied to gas to go from A to B.
