## heat capacity

n.
The ratio of the heat energy absorbed by a substance to the substance's increase in temperature. Also called thermal capacity.

## heat capacity

n
(General Physics) the heat required to raise the temperature of a substance by unit temperature interval under specified conditions, usually measured in joules per kelvin. Symbol: Cp (for constant pressure) or Cv (for constant volume)

When you multiply these two characteristics--specific heat and density--the result is a material's "volumetric heat capacity" (see chart on Page 16 for the volumetric heat capacities of common building materials).
Various explanations for equipartition's failure in describing heat capacities have been proposed.
However, the values of the densities, specific heat capacities and thermal diffusivities of the samples were found to change as the compacting pressure increased due to decreased in porosity.
Clearly the values of both the predicted and measured heat capacities are closely matched, suggesting that the dry basis MC is the dominant factor in the increase of the heat capacity, as expected.
The specific heat capacities and thermal conductivity of the shell and insulating material as well as external heat transfer coefficient are the main parameters that influence the temperature curves of the casting and shell.

The specific heat capacities of technological oil shale, oil shale coke and oil shale concentrate.
Equation 4c indicates that the minimum rate of heating also varies directly with the heat load, but unlike the maximum rate, it decreases with the total heat capacity of the system, which is the sum of the room and rack mass heat capacities.
Heat capacities are of course parameters in any dynamical model of a thermal system, and it is an appalling dismissal to suggest that climate scientists haven't heard of the things.
This change in heat capacity at the glass transition can be calculated as the difference between the heat capacities before and after the transition region.
The ability to measure absolute heat capacities allows examination of biopolymer solution conformation and solvation as well as subtle changes in folding rather than just complete unfolding.
