Critical point (thermodynamics)

Critical point in thermodynamics is a state where matter cannot be changed from one phase to another, like liquid to gas. It means that the matter doesn't change and will stay in the same form, no matter what happens. It happens when the temperature and pressure of the matter are at the exact same level.
