Question

Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason R. 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 :

Select the correct option:

A

A is correct but R is not correct

B

A is not correct but R is correct

C

Both A and R are correct and R is the correct explanation of A

D

Both A and R are correct but R is not the correct explanation of A

✓ Correct! Well done.
