Question

Assertion (A): Pipes carrying water often burst in cold countries during severe winter.

Reason (R): Water expands on freezing.

1. Both A and R are true and R is the correct explanation of A
2. Both A and R are true but R is not the correct explanation of A
3. A is true but R is false
4. A is false but R is true
5.

Answer 1

Correct Answer - Option 1 : Both A and R are true and R is the correct explanation of A

The logic that follows here is:

Assertion (A): Pipes carrying water often burst in cold countries during severe winter → True

Reason (R): Water expands on freezing → True

Most of the liquids show simple behavior, when they cooled they shrink except for the water. When water is cooled, it shrinks until a temperature of 40C is reached. After that, it expands until the water reaches its freezing point, and then when it freezes it expands more up to a certain extent. Therefore, both A and R are true and R is the correct explanation of A.

Hence, the correct answer is Both A and R are true and R is the correct explanation of A.
