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)

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.
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.
Figure 2 shows the heat capacities that were determined for a series of polypropylene-fiberglass composites for temperatures ranging from 100 [degrees] C to 250 [degrees] C.
Again, we have to remember that the specification is for PS and we are molding PP, and the densities and specific heats or heat capacities are different.
