Assertion : A piece of ice floats in water, the level of water remains unchanged when the ice melts completely.
Reason : According to Archimede's principle, the loss in weight of the body in the liquid is equal to the weight of the liquid displaced by the immersed part of the body.

A

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

B

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

C

If assertion is true but reason is false.

D

If both assertion and reason are false .

Text Solution

Verified by Experts

The correct Answer is:
A
Here the weight of immersed part of ice is same as that of the weight of water displaced by it. So the water level remains unchanged.
