A closed system undergoes a cycle consisting of two processes. During the first process, which starts at an initial system pressure of 1.00 atm and system temperature of 300K, 60 kJ of heat is transferred from the system while 25 kJ of work is done on the system. At the end of the first process, the system pressure is 0.5 atm. During the second process, 15 kJ of work is done by the system. The temperature and pressure of the surroundings are constant throughout at 300K and one atm, respectively. Determine Q, W, ΔU and ΔH for the cycle
