Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In an adiabatic process, change in internal energy of a gas is equal to work done on the gas in the process. Reason (R) : Temperature of gas remains constant in a adiabatic process. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

ABoth (A) and (R) are true and (R) is the correct explanation of (A).
BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
C(A) is true but (R) is false.
D(A) is false but (R) is true.

Correct answer

C. (A) is true but (R) is false.

Step-by-step solution

\begin{aligned} & Q=W+\Delta U \\ & Q=0 \\ & \Delta U=-W \end{aligned}
