A critical point (or critical state) is the end point of a phase equilibrium . Triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium . read more
Difference Between Critical Point and Triple Point Definition Critical point: The critical point is the endpoint of its phase equilibrium curve and defined by its critical temperature and the critical pressure. read more
Key Difference – Critical Point vs Triple Point Critical point and triple point are terms used to explain temperatures and pressures at which two or more phases of substances can coexist with each other. The critical point is the condition at which the liquid and vapour phase of the same substance coexist. read more
