Question

Assertion (A): The value of $\Delta E$ is negative if the internal energy of a system increases.

Reason (R): The value of $Q$ is negative if heat is absorbed by the system.

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

Answer 1

The correct option is D Both A and R are false

The value of $\Delta E$ is positive if the internal energy of a system increases. The value of $\Delta Q$ is positive, if heat is absorbed by the system.
