Specific heat is defined as the amount of heat required to raise one unit of mass of the substance by 1 unit of temperature. Mathematically, it is the heat capacity of a substance divided by its mass. The formula for specific heat is: Here, c is specific heat and has units J/kg.K, ...
How is the heat of combustion calculated? The heat of combustion is calculated using the heat of combustion equation. This formula is based on the calorimeter study and has as important parameters the mass of water in the calorimeter, the specific heat of the water, and the temperature change...

The temperature of a solid and liquid element rises when we supply heat to it. If we supplied the same amount of heat to two different kinds of solid then rise in temperature may be different in both the solids.This is the Specific heat Capacity.
For the calculation of the specific heat capacity at constant volume, cv some relationships are available. An exact thermodynamic derivation leads to the equation: (5.9)Cp−Cv=α2VT/κ where V is the molar volume (mol m−3), α is the expansion coefficient (K−1), and K is the ...
The specific heat of mercury is 27.8 J/mol-K. Thus, n = 5 mol C = 27.8 J/mol-K ΔT = 10 K q = ? Plugging this into the equation gives: q=5molHg(27.8Jmol∗K)(10K) So the amount of heat required to heat 5 mol of Hg by 10 K is: q=1390J You can also make use ...
