2022年9月21日 · A vapor pressure curve is a graph of vapor pressure as a function of temperature. To find the normal boiling point of liquid, a horizontal line is drawn from the y-axis at a pressure equal to standard pressure.
Vapor pressure - Wikipedia
Vapor pressure[a] or equilibrium vapor pressure is the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapor pressure is an indication of a liquid's thermodynamic tendency to evaporate.

2023年1月30日 · Vapor pressures have an exponential relationship with temperature and always increase as temperature increases (Figure 2: Vapor Pressure Curves). It is important to note that when a liquid is boiling, its vapor pressure is equal to the external pressure.

2020年8月14日 · To understand that the equilibrium vapor pressure of a liquid depends on the temperature and the intermolecular forces present. To understand that the relationship between pressure, enthalpy of vaporization, and temperature is given by the Clausius-Clapeyron equation.
Normal boiling point: temperature at which the liquids vapour pressure equals 1 atm. Triple point: the temperature and pressure at which the solid, liquid and gas are at equil. Vapourization curve: at any point on this line (specified by a temperature and pressure) the liquid and gas are at equilibrium. liquid are at equilibrium.

2024年12月5日 · A vapor pressure curve is a graph of vapor pressure as a function of temperature. To find the normal boiling point of a liquid, a horizontal line is drawn from the left at a pressure equal to standard pressure.
Vapor Pressure - Purdue University
The vapor pressure of a liquid is the equilibrium pressure of a vapor above its liquid (or solid); that is, the pressure of the vapor resulting from evaporation of a liquid (or solid) above a sample of the liquid (or solid) in a closed container.

We can better understand the information represented by the vapor pressure curve by looking at the process of isobaric heating. This is illustrated by line ACB in Figure 3.1.2. The term “isobaric” pertains to a constant pressure process. By isobaric heating process, we then mean a “constant pressure addition of heat into a system.”
In Figure 2 we have added the lower curved line from "Tol VP" to "Bz VP" to show the composition of the vapor at each pressure. The region between the curved line and the straight total vapor pressure line is a two phase region.
