What is the thermal conductivity of air at 300 K?
The nominal values used for air at 300 K are CP = 1.00 kJ/kg.
What is K CP?
Thermodynamic comparison (k = cp/cv) of the ratio of a specific heat (k) at a constant pressure (cp) to a specific heat at a constant volume (cv). The ratio range for most gasses is 1.2 to 1.4.

What is the state of carbon dioxide at 190 C?
solid
Some substances can change directly from solid to gas, or from gas to solid, without becoming a liquid in between. This is called sublimation . Solid carbon dioxide (‘dry ice’) and iodine can sublime ….Predicting a physical state.

What is the specific heat of water in J kg K?
4184 joules
The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.
What are the properties of gas at 300 K?

When to use specific heat for carbon dioxide?
When calculating mass and volume flow of a substance in heated or cooled systems with high accuracy – the specific heat should be corrected according values in the table below. Specific heat of Carbon Dioxide gas – CO2 – at temperatures ranging 175 – 6000 K: The values above apply to undissociated states.
How is the solubility of CO2 measured in water?
J/ (mol·K) ‡Second column of table indicates solubility at each given temperature in volume of CO2 as it would be measured at 101.3 kPa and 0 °C per volume of water. The solubility is given for “pure water”, i.e., water which contain only CO 2. This water is going to be acidic.
What are the physical properties of carbon dioxide?
Physical properties. Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 5.1 bar (517 kPa) at 217 K (see phase diagram). The critical point is 7.38 MPa at 31.1 °C. Another form of solid carbon dioxide observed at high pressure is an amorphous glass-like solid.
