Two bodies A and B are of same mass, and same amount of heat is given to both of them. If the temperature of A increases more than that of B because of heat addition, then

The relationship between heat transfer (Q), mass (m), specific heat capacity (c), and temperature change (ΔT) is defined by the formula Q = mcΔT [t1][t6]. In this scenario, both bodies A and B have the same mass (m) and receive the same amount of heat (Q). Rearranging the formula to ΔT = Q / (mc) shows that the temperature change is inversely proportional to the specific heat capacity [t1][t3]. Since the temperature of body A increases more than that of body B (ΔT_A > ΔT_B), body A must have a lower specific heat capacity than body B [t3][t5]. Specific heat capacity is an intrinsic property representing the energy required to raise the temperature of a unit mass by one degree [t2][t5]. Thermal conductivity relates to the rate of heat transfer through a material rather than the total temperature rise for a given quantity of heat [c3][t8].
