WebThe table below gives thermodynamic data of liquid CO 2 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. WebUsing the phase diagram of carbon dioxide, describe the following conditions as stated below. 1. What happens when the follovving changes are made in a CO2 sample, which initially records at 1 atm. and -60°C? (a) Pressure increases at a constant temperature to 80 atm. (b) Temperature increases from -60°C to -18°C at constant 80 atm.pressure.
WebSo in the first part we have to find the phase of the carbon dioxide at 25 18 pressure and -65°C temperature. So the temperature is here -78.5. And So the temperature -65 will be slightly here. So this will be -65°C temperature. And the … WebIn part (b) in Figure 11.23 "Two Versions of the Phase Diagram of Water", point A is located at P = 1 atm and T = −1.0°C, within the solid (ice) region of the phase diagram. As the pressure increases to 150 atm while the temperature remains the same, the line from point A crosses the ice/water boundary to point B, which lies in the liquid water region.
