Question

Assertion (A): It becomes very cold after the hail storm.

Reason (R): Ice has a high specific heat capacity of 2.1 Jg⁻¹°C⁻¹.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Assertion (A) is true, but Reason (R) is false.

Explanation:

After a hail storm, the hailstones melt and absorb a large amount of latent heat from the surroundings, so it becomes cold. This is due to the high specific latent heat of fusion of ice, not due to a high specific heat capacity. Also, the specific heat capacity of ice (2.1 Jg⁻¹°C⁻¹) is not high compared with water. Hence, R is false.
