How do you find the temperature of CO2?
How much warming does carbon dioxide itself contribute to the current surface temperature of the Earth? We can calculate the CO2 flux density (F) at concentration C in the current atmosphere using the fundamental equation: F = 5.35 ln C. Water vapour adds a further 75 W/m2 giving total ΔF = 107.05 W/m2.
What is CP of air?
The nominal values used for air at 300 K are CP = 1.00 kJ/kg. K, Cv = 0.718 kJ/kg.
Why is CP is greater than CV?
The molar heat capacity at constant pressure is represented by Cp. At constant pressure, when a gas is heated, work is done to overcome the pressure and there is an expansion in the volume with an increase in the internal energy of the system. Therefore, it can be said that Cp is greater than Cv.
How do you calculate CP of a gas?
cp = cv + R The specific heat constants for constant pressure and constant volume processes are related to the gas constant for a given gas.

What is the concentration of carbon dioxide in flue gas?
Carbon dioxide is a component of all flue gases produced by the complete combustion of carbonaceous fuels. Typical concentrations of carbon dioxide in such gases are 10 – 18 vol%.
