Forráspontgörbe

Forráspontgörbe refers to a phase diagram that illustrates the relationship between pressure and temperature at which a pure substance exists in equilibrium between its liquid and gaseous phases, specifically depicting the boiling point at different pressures. The curve starts at the triple point, where solid, liquid, and gas coexist, and extends to the critical point, beyond which the distinction between liquid and gas disappears. As pressure increases along the forráspontgörbe, the boiling point also increases because more energy is required to overcome the higher external pressure and allow the liquid to vaporize. Conversely, at lower pressures, the boiling point is lower. This concept is fundamental in understanding the behavior of substances under varying conditions and is crucial in fields like chemistry, physics, and engineering, particularly in distillation and phase transition studies. The shape of the forráspontgörbe is characteristic of each individual substance.
