Assertion: The internal energy of an ide...

Assertion: The internal energy of an ideal gas does not change during an isothermal process.
Reason: The decrease in volume of a gas is compensated by a corresponding increase in perssure, when its temp. is held constant.

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:
B
In isothermal process, temperature remains constant. Therfore, inernal energy of an ideal gas does not change-as it is dependent only of temperature- neither on pressure nor on volume. So the assertion is true but the reason is not a correct explanation of the assertion.
