WebHeat the crucible again for a couple of minutes and once again allow to cool. Repeat this step until the mass readings are consistent. This is known as heating to constant mass. Teaching notes. Students should have … WebIn the derivation of , we considered only a constant volume process, hence the name, ``specific heat at constant volume.''It is more useful, however, to think of in terms of its definition as a certain partial derivative, which is a thermodynamic property, rather than as a quantity related to heat transfer in a special process. In fact, the derivatives above are …
