Question
Which property of a substance determines the amount of heat required to change its temperature by 1∘C per unit mass?
Explanation
Specific heat capacity (s) is defined as the heat required per unit mass to change the temperature by 1∘C (Section 10.6, s = 1mΔQΔT). As per NCERT, applying relevant law/formula with correct units and sign convention leads to Specific heat capacity. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
