Assertion: The increase in internal energy `(DeltaE)` for the vaporisation of 1 mole of water at 1 atm and `373K` is zero.
Reason: For all isothermal processes `DeltaE=0` .

A

If both ther assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both the assertion and reason are true but reason is not the correct explantion of the assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B

The assertion that the increase in internal energy for the vaporisation of 1 mole of water at 1 atm and `373K` is zero is true because for all isothermal process internal energy is zero.
