Which outcome accompanies isentropic compression within a refrigeration cycle?

A)Increased refrigerant temperature and pressure
B)Reduced refrigerant temperature; constant entropy
C)Constant refrigerant temperature; expanded volume
D)Decreased refrigerant pressure; increased entropy

💡 Explanation

Isentropic compression, part of a refrigeration cycle, increases both temperature and pressure because it's an adiabatic process with no heat exchange. The refrigerant's internal energy rises due to work done, therefore A is correct, rather than B, C, or D which involve entropy decrease.
