Webof thermodynamics and thus CC TV PV 2 −=α κ cannot be negative. It is well known that α can be zero, e.g., for water at ∼4 °C. In this case, CP equals CV. Can κ be zero too? No. If any substance had a zero κ, its α value would have to be zero to avoid the difference between CP and CV approaching infinity. WebNote that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules.If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol −1 ⋅K −1 = 3 R …
