Final answer:

The critical point represents a state where liquid and gas phases merge due to specific temperature and pressure conditions of a substance.


Explanation:

The critical point of a substance is the combination of temperature and pressure above which the liquid and gas phases are indistinguishable, marking the intersection of critical temperature (Tc) and critical pressure (Pc). At the critical point, a supercritical fluid exists where a gas cannot be liquefied above the critical temperature, regardless of pressure.
