//*****Data*****//
m = 1;// [kg]

Th = 295;// [K]
Ql = 335;// [kJ/kg]
//*************//
// Solution (a)
// The coeffecient of performance of refrigerating machine is:
// COP = Ql/Wnet = Tl/(Th - Tl)
Wnet = Ql*(Th - Tl)/Tl;// [kJ]
printf("Minimum Work requirement is %d kJ\n",round(Wnet));
// Solution (b)
// Amount of heat released:
// Wnet = Qh - Ql
Qh = Wnet + Ql;// [kJ]
printf("Amount of heat released to the surrounding is %d kJ\n",round(Qh));
