Question

define
the critical state of gas​

Answer 1

Answer:

Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. ... The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied

Explanation:

Answer 2

Answer:

In thermodynamics, a critical point is the end point of a phase equilibrium curve. The most prominent example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist.
