Question

Critical pressure of co2 gas is​

Answer 1

Explanation:

More specifically, it behaves as a supercritical fluid above its critical temperature (304.13 K, 31.0 °C, 87.8 °F) and critical pressure (7.3773 MPa, 72.8 atm, 1,070 psi, 73.8 bar), expanding to fill its container like a gas but with a density like that of a liquid.

Answer 2

• At the critical temperature above which different liquid and gas phases do not exist, the critical pressure is the vapour pressure of a fluid. The properties of the gas and liquid phases become the same as the critical temperature is reached, resulting in just one phase.

• Critical Point is the point on a phase diagram in temperature and pressure where a substance’s liquid and gaseous phases combine together into a single phase. The fused single phase is known as a supercritical fluid above the temperature of the critical point.
• The critical temperature and pressure of CO2 gas are 304.2 K and 72.9 atm respectively.
