In a refrigerator, 2.00 mol of an ideal monatomic gas are taken through the cycle shown in the figure. The temperature at point A is 800.0 K.

(a) What are the temperature and pressure at point D?
(b) What is the net work done on the gas as it is taken through four cycles?
(c) What is the internal energy of the gas when it is at point A?
(d) What is the total change in internal energy of this gas during four complete cycles?
