Heat and Thermodynamics question

2023 · 29 Jan · Shift 1 · Q53

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: If dQd QdQ and dWd WdW 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−dWd Q=d U-d WdQ=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 options given below:
  1. A
    Both A and R are correct but R is not the correct explanation of A
  2. B
    Both A and R are correct and R is the correct explanation of A
  3. C
    A is correct but R is not correct
  4. D
    A is not correct but R is correct
