the clausius inequality places which restriction on an actual cycle? a- net heat transfer must be positive b-net het transfer must be negative c-differential quantity og dq?t must be negative d- the ifferential quantity of dq/t must be positive. there can be two correct answers

Solution

KAns Clausius inequality states that the differential dq/dt for a cyclic process must be negative that is the entropy of the system for cyclic process is always greter than or equal to zero.Thus it also puts a restriction on the heat transfer.Net heat transfer must be positive for the system.Thus A and D are correct
