At very low temperatures, the molar heat capacity of rock salt varies with temperature according to debyeâs t 3 law: c = k t 3 î¸ 3 , where k = 1940 j/(molâ·k) and î¸ = 281 k.
a. weâve learned the relation q = ncât for the molar heat capacity, which works well when the molar heat capacity is a constant. how do you think we should handle a situation in which the heat capacity varies with temperature? (hint: this is what calculus is how did we calculate work by a force that varies with position, like the force from a spring? ) find a way to calculate the amount of heat required to raise the temperature of 1.50 mol of rock salt from 11.0 k to 45.0 k; show your work and explain your reasoning.
