Assertion : The angle of contact of a lilquid with a solid decreases with increase in temperature.
Reason : With increase in temperature, the surface tension of the liquid increases.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts
