Statement-1 : In an adiabatic process, change in internal energy of a gas is equal to work done on/by the gas in the process.
Statement-2 : This is because temp.of gas remains constant in an adiabatic process.

A

If both, Assertion and Reason are true and Reason is the correct explanation of the Asserrion.

B

If both,Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Internal energy of an ideal gas does not depends upon volume of gas, because there are no forces of attraction/repulsion amongst the molecules of an ideal gas. Statement-1 is true, but statement-2 is false.
