    Hard molar specific heat question?

    Could you tell me how to get the C value for this question? I know C=k*(T^3/To^3) from the problem, it also gives me k and To value, but I don't know what is T value.

    Hard molar specific heat question?

    Homework Statement At very low temperatures, the molar specific heat of many substances varies as the cube of the absolute temperature: C=k*(T^3/To^3), which is sometimes called Debye's law. For rock salt, To= 281K and k= 1940 J/mol*K Determine the heat needed to raise 2.40 mol of salt from...
