molecular heat

Neumann's law states that the molecular heat in compounds of analogous constitution is always the same.

Some may consist of goofily slack-jawed faces that recall Daumier; in others, looping thatches of abstract lines create a fizzy, molecular heat.

This means as temperature rises, translational, vibrational, and rotational contributions to molecular heat capacity let molecules absorb heat and hold more internal energy.

After teaching in a high school, he became an assistant professor in applied physics at the University of Sciences and accomplished valuable theoretical work investigating specific heat and molecular heat.

His 1831 study on the specific heats of compounds included what is now known as Neumann's Law: the molecular heat of a compound is equal to the sum of the atomic heats of its constituents.

Kopp found "that the molecular heat capacity of a solid compound is the sum of the atomic heat capacities of the elements composing it; the elements having atomic heat capacities lower than those required by the law of Dulong and Petit retain these lower values in their compounds."
