Question

Assertion :Water in a beaker cannot be made to boil by placing it in a bath of boiling water. Reason: Water in the beaker will be heated to ${100}^{o}C$ but will not boil as for boiling it requires latent heat of steam which is not provided by water bath as both attains ${100}^{o}C$.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Assertion is incorrect but Reason is correct.

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

Water in a beaker cannot be made to boil by placing it in a bath of boiling water.

Assertion is true.

For water in a beaker to boil, it requires latent heat of vaporization which won't be provided by the bath of boiling water. Water in bath and water in a beaker will attain thermal equilibrium.

Hence, reason given is the correct explanation of the assertion.

So, option A is correct
