Question

Assertion (A): Heat capacity is the amount of heat energy required to raise the temperature of a given mass of the body by 1°C.

Reason (R): Specific heat capacity is the amount of heat energy required to raise the temperature of unit mass of the body by 1°C.

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

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

Explanation:

The assertion is true because heat capacity is the heat energy required to raise the temperature of a given mass of a body by 1°C (or 1 K). The reason is also true because specific heat capacity is the heat energy required to raise the temperature of a unit mass of a body by 1°C. However, the reason gives the definition of specific heat capacity, not the explanation of heat capacity. Therefore, both are true but R is not the correct explanation of A.
