A : Heat absorbed in a cyclic process is zero.
R : Wrok done in a cyclic process is zero.

A

If both Assertion & Reason are true and the reason is the correct explantion of the assertion, then mark(1)

B

If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).

C

If Assertion is true statement but Reason is false, then mark (3).

D

If both Assertion and Reason are false statements, then mark (4)

The correct Answer is:
To analyze the statements given in the question, we need to evaluate both the assertion (A) and the reason (R) in the context of thermodynamics, particularly focusing on cyclic processes. ### Step-by-Step Solution: 1. **Understanding Cyclic Processes:** - A cyclic process is one where a system returns to its initial state after undergoing a series of changes. This means that the initial and final conditions (pressure, volume, temperature) of the system are the same. 2. **Assertion (A): Heat absorbed in a cyclic process is zero.** - This statement is **incorrect**. In a cyclic process, while the change in internal energy (ΔU) is zero, it does not imply that the heat absorbed (Q) is zero. The heat exchanged can be positive or negative depending on the specific path taken in the process. 3. **Reason (R): Work done in a cyclic process is zero.** - This statement is also **incorrect**. In a cyclic process, the net work done (W) can be non-zero. The work done is related to the area enclosed by the path on a PV diagram. If the process involves expansion and compression, the work done can be positive or negative, leading to a net work output. 4. **Conclusion:** - Since both the assertion (A) and the reason (R) are incorrect, we conclude that neither statement is true in the context of a cyclic process. ### Final Answer: Both A and R are incorrect.
