Heat capacity at constant volume \(C_v\), is defined as \[ C_v = \left(\dfrac{\partial U}{\partial T} \right)_v\] The equipartition theorem requires that each degree of freedom that appears only quadratically in the total energy has an average energy of ½k B T in thermal equilibrium and, thus, contributes ½kB to the system's heat capacity. Calculation of thermodynamic state variables of carbon dioxide . The molar heat capacity of a chemical substance is the amount of energy that must be added, in the form of heat, to one mole of the substance in order to cause an increase of one unit in its temperature.Alternatively, it is the heat capacity of a sample of the substance divided by the amount of substance of the sample; or also the specific heat capacity of the substance times its molar mass.

The theoretical heat capacity ratio for nonlinear CO2 would be 6/2R. Heat Capacity of Gaseous Carbon Dioxide Joseph F. Masi and Benjamin Petkof The heat capacity (Cp) of gaseous carbon dioxide has been measured at —30°, 0°, +50°, and +90° C and at 0.5-, 1.0-, and 1.5-atmosphere pressure, with an accuracy of 0.1 percent. The mass of one molecule of CO2 is 7.308 x 10^-23g or 7.308 x 10^-26kg and the Specific Heat Capacity of CO2 is 834 at constant pressure (J kg-1K-1) In essence, I am looking for both the value and the formula for which to use in order to calculate this. Ref. However, NIST makes no warranties to that effect, and NIST Feel free to prove me wrong…right after you debunk the 1st Law of Thermodynamics. All things being equal, a bottle filled with CO 2 will always warm faster and to a higher temperature when heated than does a bottle filled with regular air because the specific heat of CO 2 is lower than that of air. Technology, Office of Data Carbon monoxide interferes with the distribution of oxygen in the blood to the rest of the body. with the development of data collections included in 56 (1934) 1838-1842, Gordon A.R. The heat capacity at constant volume, C v, is the derivative of the internal energy with respect to the temperature, so for our monoatomic gas, C v = 3/2 R. The heat capacity at constant pressure can be estimated because the difference between the molar C p and C v is R; C p – C v = R. : Thermodynamic functions of nitrous oxide and carbon dioxide..
