Figure 2: Heat capacity at constant volume of a substance.
The heat capacity at constant volume of a substance is shown as a function of temperature T
on the Kelvin scale in the figure. At low temperatures, it rises as aT³, saturating at a value
b after a critical temperature T..
(a) Calculate the entropy of the substance as a function of temperature, stating any as-
sumptions you make and assessing your answer.
(b) Considering only temperatures T < Tc; calculate the internal energy of the substance
as a function of temperature. Again, state any assumptions you make and assess your
answer.
