Table of specific heat capacities - Wikipedia

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 per mole of atoms (see the last column of this table). Paraffin for example has very large molecules and thus a high heat capacity per ...

Everything You Need To Know About Acrylic (PMMA)

By contrast thermoset plastics can only be heated once (typically during the injection molding process). The first heating causes thermoset materials to set (similar to a 2-part epoxy) resulting in a chemical change that cannot be reversed. If you tried to heat a thermoset plastic to a high temperature a second time it would simply burn.

Specific heat capacity of plastics? | Yahoo Answers

The material having high specific heat capacity can absorb more amount of heat than with low specific heat capacity. The material having low specific heat capacity absorbs and loses heat faster but it is just opposite in the material having high specific heat capacity i.e the material having high specific heat capacity remains hot for longer time.

5.2 Specific Heat Capacity - Chemistry LibreTexts

Specific Heat Capacity. The specific heat capacity is the amount of heat it takes to change the temperature of one gram of substance by 1°C. So we can now compare the specific heat capacity of a substance on a per gram bases. This value also depends on the nature of the chemical bonds in the substance and its phase.
