Critical Point In Pure Substance
- The critical point in pure substance is the highest temperature and pressure at which a pure substance can prevail in vapour or liquid equilibrium.
- At temperatures that are higher than the critical temperature, the substance can not prevail as a liquid, where it does not matter about the pressure.
- At temperatures and pressures that are higher than the critical point then the substance has deemed a fluid or something that is neither gas nor liquid.
- At pressures that are lower than the critical pressure but at higher temperatures then the substance has been deemed a gas.
- The curves of the three-phase equilibrium will meet at the triple point. At the triple point, all three phases which are solid, liquid, and gas are in an equilibrium state.
