QUESTION 6
Background
To calculate an accurate value for the heat Q required to change the temperature of copper from 4 K to 20 K,
molar specific heat of copper over this range of temperature,
Cmoi=1940 (T/e) ] mol-1 K-1
%3D
where the "Debye Temperature e" has the value e = 348 K for copper. In order to account for the temperature
for the differential heat dO = C dT and integrate to find the total heat Q required,
-Tfrol
C dT
Remember that the upper case C in this expression is the temperature-dependent heat capacity, which needs t
molar specific heat and the number of moles.
