Answer
assertion is true but reason is false.
Explanation
Assertion (A) is true. The specific heat capacity of a substance is the amount of heat required to raise the temperature of unit mass of the substance by 1°C (or 1 K).
Reason (R) is false. The specific heat capacity of a substance is its characteristic property. It represents the substance's ability to store heat energy per unit mass and is an intrinsic property that is unique to each substance.
