Aclosed system of monatomic ideal gas is taken through a three-step cycle. the system starts in state 1, which has a pressure p and a volume v. then, an expansion at constant pressure occurs (process a), taking the system to state 2, where the volume is 3v. this is followed by process b, an isothermal compression that bring the system to state 3, where the pressure is 3p and the volume returns to v. finally, a constant-volume process (process c) returns the system to state 1. for this problem, take p to be 90.0 kpa and take v to be 6.00 liters. remember that heat is positive when it is added to the system, and negative when it is removed from the system.

(a) calculate the heat in the a process. j
(b) calculate the heat in the b process. j
(c) calculate the heat in the c process. j
(d) calculate the heat in the entire process. j
