Why does a substance with high specific heat capacity take longer to heat up?
A high specific heat capacity means more heat (ΔQ = msΔT) is required per unit mass to raise the temperature, slowing the heating process (Section 10.6). As per NCERT, applying relevant law/formula with correct units and sign convention leads to It requires more heat per unit temperature rise. This satisfies dimensional consistency and physical conditions given, so option D is scientifically correct.
