    Change in Free Energy when Heating a Substance

    Hello DrDu, thank you very much for your explanation. Si I just take the the Shomte equation for enthalpy S(T), integrate it from T1 to T2, and that should be it? Thanks!

    Change in Free Energy when Heating a Substance

    Hello everyone! I'm new to the forum, and I've been trying to solve a problem that seems farily but I can't still convince myself of having the right (or wrong) answer. Imagine you warm up one mol of for example potassium hydride from standard temperature 298.15K to 673.15K (400 deg C). It is...
