Question

Assertion (A): Calorimeter is always made from copper vessel.

Reason (R): The heat capacity of a calorimeter is very large.

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:

A calorimeter is made of a thin copper vessel so that its heat capacity is very small and it absorbs negligible heat energy. Hence, the assertion is true. The reason is false because a calorimeter's heat capacity should be small, not very large.
