Solution
a) Describe the phase changes and the temperature at which they occur when CO2 is heated from -80C to 200C at contant pressure of 100 bar,
Solution :- At -80 to 200 C change in temperature at 100 barr the solid CO2 will change into gas
b) Describe the phase changes and the temperature at which they occur when CO2 is heated from -80C to 200C at constant perssure of 500 bar.
Solution : - for the temperature change from -80 to 200 C and pressure 500 bar liquid will change to supercritical fluid.
c) Describe the phase changes and the temperature at which they occur when CO2 is heated from -80C to 20C at contant pressure of 1000 bar
Solution :- for the temperature change from -80 to 20 C at 1000 bar pressure liquid will change to gas
d) Describe the phase changes and the temperature at which they occur when CO2 is heated from -80C to 1000C at contant pressure of 1000 bar
Solution : - for the temperature from -80 C to 1000 C at constant pressure 1000 bar solid will change to supercritical fluid.
