Aluminum is reactive at a pH > 9 and pH < 4, so I can't use it strongly acidic/basic samples. The other common DSC materials are all metals that are fairly reactive as well. The ideal pan...

In thermodynamic tables of liquids, S is usually given without mention of constant volume or constant pressure. In solids this makes sense because Cv ~ Cp, so S should be the same. In liquids, Cp...
