The specific heat capacity of solid copper metal is 0.385 J/gK. How many Joules of heat are needed to raise the temperature of a 1.05-kg block of copper from 25.0 ^oC to 66.0 ^oC? a. 1.66 x 10^4 J b. 18.2 J c. 1.82 x 10^4 J d. 8.17 x 10^{-6} J e. ...
When 629.0 J of heat energy is added to a 50.5 g sample of solid copper, the temperature increases to 87.8 degrees C. What was the original temperature of the solid in degrees C? The specific heat capacity of solid copper is 0.385...
Specific heat capacityCore-shellNanoencapsulated materialsShellInterfaceIn this paper, we firstly develop the shell and core-shell HC models for the first time. Then, the differential scanning calorimeter (DSC) method is applied to measure HCs of copper nanoparticles, carbon shells and core-shell/Cu...

A manganin heater was wound around the body of the calorimeter and a carbon thermometer, embedded in a copper sleeve with araldite, was clamped inside a re-entrant copper block which formed part of the bottom of the calorimeter. A mechanical heat switch permitted cooling of the calorimeter....
One of the problems that has to be considered when calculating specific heat of astro-material is that the minerals are usually neither perfectly mechanically mixed nor do they show solid solutions of the same composition throughout the sample of interest. This is clear from the study of meteorit...
