WebThe evaporation latent heat of CO2 is large and the refrigerating capacity per unit volume is high (22.6 MJ/m3 at 0 ℃), about 5 to 8 times that of traditional refrigerants. The kinematic viscosity of CO2 is very low and can remain at low temperatures. The thermal conductivity of CO2 is high, and the ratio of liquid density to vapor density is ...
WebThe specific heat capacity of liquid water is 29.0 A 6.55 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter. If the temperature rose by 32.9°C, use the information below to determine the heat capacity of the calorimeter. 4 C6H5NH2 (l) + 35 O2 (g) → 24 CO2 (g) + 14 H2O (g) + 4 NO2 (g) ΔH°rxn = -1.28 x 104 kJ WebThe test results show much lower permeability values for liquid CO2 than gaseous CO2, ... (22 °C and 6 MPa) is 6.27 kJ/mol, and it is much higher than the heat capacity of gaseous and liquid CO 2 which are around 36.6 J/mol·°C and 133.8 J/mol·°C, respectively.
The table below gives thermodynamic data of liquid CO2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 °C temperature and 3483 kPa pressure. To convert heat values to joules per mole values, multiply by 44.095 g/mol. To convert densities to moles per liter, multiply by 22.678 cm mol/(L·g).
