Assertion: If water is kept in an open container on the surface of moon, it will quickly evaporate.
Reason: Moon's surface temperature is greater than the boiling point of water.

A

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

B

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

C

If assertion is correct but reason is incorrect.

D

If assertion is incorrect but reason is correct.

Text Solution

Verified by Experts

The correct Answer is:
C
Due to low gravity on moon, escape velocity is small and hence no atmosphere is there thus reducing atmospheric pressure and evaporation of water is quicker
