Assertion. A bubble comes from the bottom of a lake to the top.
Reason. Its radius increases.

A

both Assertion and Reason are true and the Reason in the correct explanation of the Assertion.

B

both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

Assertion is true but the Reason is false.

D

both Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Here, both Assertion and Reason are true but reason is not correct explanation of Assertion. When bubble moves from the bottom to top (i.e., from higher pressure to lower pressure) pressure on it decreases and its volume and hence radius increases.
