body heat capacity can be found from the following formula.

• body heat capacity can be found from the following formula.
• Cx=(t-t0)(Ccmc+Ckmk)/mx(tx-t), 
•  where mx, mc, and mc are the masses of the body, fluid, and calorimeter, respectively.

The theory of heat capacity of gases is very developed. Heating at normal temperatures mainly leads to changes in the energies of forward and rotational movement of gas molecules. The theory gives 3R/2 for the molar heat capacity Cv of monatomic gases, and 5R/2 and 3R for diatomic and polyatomic gases. At very low temperatures, the heat capacity is slightly smaller due to quantum effects. At high temperatures, vibrational energy is added, and the heat capacity of polyatomic gases increases with temperature.
