Final answer:
The heat transfer per unit mass depends on the substance's mass, the temperature change, and the specific heat capacity, expressed mathematically as q = c × m × ΔT.
Step-by-step explanation:
The amount of heat (q) transfer per unit mass of a substance is related to the mass of the substance (m), the change in temperature (ΔT), and the substance's specific heat capacity (c). The relationship is described mathematically as q = c × m × ΔT, where q is the amount of heat transferred, c is the specific heat capacity of the material, m is the mass, and ΔT is the temperature difference, being Tfinal - Tinitial. This formula shows that the heat transfer is directly proportional to both the mass and the temperature change, and it also depends on the specific heat capacity of the material.
