Question

At critical temperature pressure and volume the compressibility factor is

Answer 1

Answer:

Critical Temperature, Volume, and Pressure

With the increase in temperature, the pressure required to liquefy a gas also increases. This temperature was the highest temperature at which a gas appears in the form of a liquid. ... Critical constants are critical pressure, temperature, and volume.

Answer 2

Answer:z<1

Explanation: at critical condition the value of z is 0.375

Z=Pc×Vc÷R×Tc
