What is the heat of vaporization of CO2?
6030 cal.
The heat capacity of solid carbon dioxide has been measured from 15 to 195°K. The heat of vaporization at the sublimation point, 194.67°K, was found to be 6030 cal./mole.
What is the latent heat of sublimation of CO2?
571 kJ/kg
The low temperature and direct sublimation to a gas makes dry ice an effective coolant, since it is colder than water ice and leaves no residue as it changes state. Its enthalpy of sublimation is 571 kJ/kg (25.2 kJ/mol).
What is the standard entropy of CO2?
Entropy of gas at standard conditions (298.15 K, 1 bar.)
| S°gas,1 bar (J/mol*K) | 213.79 |

How do you find the specific heat of CO2?
Isobaric specific heat (Cp) is used for substances in a constant pressure (ΔP = 0) system….Specific heat of Carbon Dioxide gas – CO2 – temperatures ranging 175 – 6000 K.
| Carbon Dioxide Gas – CO2 | |
|---|---|
| Temperature – T – (K) | Specific Heat – cp – (kJ/(kg K)) |
| 250 | 0.791 |
| 275 | 0.819 |
| 300 | 0.846 |
How does CO2 trap heat?
When sunlight reaches Earth, the surface absorbs some of the light’s energy and reradiates it as infrared waves, which we feel as heat. As CO2 soaks up this infrared energy, it vibrates and re-emits the infrared energy back in all directions.

What is Gamma for carbon dioxide?
The experimental values for γ, for CO2, Ar, N2 and an Ar + N2 mixture in the ratio 0.49:0.51 were found to be 1.1652 ± 0.0003, 1.4353 ± 0.0003, 1.2377 ± 0.0001 and 1.3587 ± 0.0002 respectively.
Can CO2 be liquefied?
Gaseous CO2 Gaseous CO2 can be liquefied under pressure provided its temperature is below 31 °C (87,8 °F), this temperature being referred to as the CRITICAL POINT. If compressed and cooled below the critical point, a colourless fluid, approximately the same density as water, is produced.

What is the specific heat of fusion of carbon?
Specific heat of Carbon is 0.71 J/g K. Latent Heat of Fusion of Carbon is — kJ/mol. Latent Heat of Vaporization of Carbon is 355.8 kJ/mol. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics.
What happens when carbon dioxide is heated in water?
Carbon dioxide, CO2, is a colourless and odorless gas. It is relatively nontoxic and noncombustible, but it is heavier than air and may asphyxiate by the displacement of air. When CO 2 is solved in water, the mild carbonic acid, is formed. Cooled CO 2 in solid form is called dry ice.
What are the thermophysical properties of carbon dioxide?
Carbon Dioxide – Thermophysical Properties. Carbon dioxide, CO2, is a colourless and odorless gas. It is relatively nontoxic and noncombustible, but it is heavier than air and may asphyxiate by the displacement of air. When CO 2 is solved in water, the mild carbonic acid, is formed.
