Background To calculate an accurate value for the heat Q required to change the temperature of copper from 4 K to 20 K, you must include the temperature dependence of the molar specific heat of copper over this range of temperature, Cmol=1940 (T/e) J mol-1 K1 where the "Debye Temperature e" has the value 0 = 348 K for copper. In order to account for the temperature variation of the molar specific heat, use the expression for the differential heat dQ = C dT and integrate to find the total heat Q required, Q= C dT Remember that the upper case C in this expression is the temperature-dependent heat capacity, which needs to be rewritten in terms of the temperature-dependent molar specific heat and the number of moles. Question: Calculate an accurate value for the heat Q in Joules required to change the temperature of 1.3 moles of copper from 4 K to 20 K using the temperature dependent molar specific heat just described. Do not include units in your answer. Write your answer as a number in normal form.
