Question

Assertion: In adiabatic process work is independent of path.
Reason: In adiabatic process work done is equal to negative of change in internal energy.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

For adiabatic process Q = 0 = $\Delta$ U + W
W = -$\Delta$ U
