Is there a phase change when R22 is cooled from 77.7°C to 40°C?
Thread Content
I’m seeking advice from experts: Does R22 undergo a phase change when cooled from 77.7°C to 40°C? What is the specific heat capacity of R22?
The critical pressure of R22 is 4.977 MPa, the critical temperature is 96.1°C, and the specific heat at constant volume is 101.1 J(mol·K). What is the pressure?
Under such conditions, there should be no phase transition.
Yes, the original poster’s question is too vague; if the pressure is high and it’s below the critical temperature, it will definitely liquefy. Also, heat capacity is related to temperature as well. You can’t ask in a general way.
