Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The first law of thermodynamics is based on law of conservation of mass. Reason R: Second law of thermodynamics states that heat flows from a higher temperature to lower temperature. In the light of the above statements, choose the most appropriate answer from the options given below
• Both A and R are correct and R is the correct explanation of A
• Both A and R are correct but R is NOT the correct explanation of A
• A is correct but R is not correct
• A is not correct but R is correct

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Important thermodynamics laws: First law: \[ \boxed{ \text{Conservation of energy} } \] Second law: \[ \boxed{ \text{Heat flows naturally from hot to cold} } \] Remember: \[ \boxed{ \text{First law tells “how much”, second law tells “which direction”} } \]

Answer 1

The Correct Option is D
