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.

Options

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.

Answer

C

Explanation

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.
