Question

Assertion (A): Pipes carrying water often burst in cold countries during severe winter.
Reason (R): Water expands on freezing.

Answer 1

Answer:

The assertion 'Pipes carrying water often burst in cold countries during severe winter' and the reason ' Water expands on freezing' are correct.

Explanation:

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

We notice that water pipes burst during winters. This is due to the change in the density and the volume of the water while freezing.

Reason: Water expands on freezing.

The water will behave like a normal liquid by contracting itself till 4°C and then later starts to expand. Due to the hydrogen bonding existing among the molecules, it starts getting stronger and there are several gaps, resulting in the expansion of the solid.

Conclusion:

The assertion and its reason are true and linked.
