If the boundary of a system is at zero degrees centigrade, the change in entropy dS due to heat transfer dQ is zero.Question 9Select one:a.TRUEb.FALSE

Entropy is always conserved with a system, it cannot be created or destroyed.Question 4Select one:a.TRUEb.FALSE

The entropy of a fluid can never decrease.Question 10Select one:a.TRUEb.FALSE

Assertion A : If dQ and dW represent the heat supplied to the system and the work done on the system respectively. Then according to the first law of thermodynamics dQ=dU−dW.Reason R : First law of thermodynamics is based on law of conservation of energy.In the light of the above statements, choose the correct answer from the option given below :A is correct but R is not correctA is not correct but R is correctBoth A and R are correct and R is the correct explanation of ABoth A and R are correct but R is not the correct explanation of A
