WebSep 9, 2024 · Normal boiling point is the temperature at which a liquid boils at 1 atmosphere of pressure. It's different from the simple definition of boiling point in that the pressure is defined. The normal boiling point is a more useful value when comparing different liquids, since boiling is affected by altitude and pressure. WebThis means that if you know the boiling point of a substance at 1 atm (the normal boiling point), and you know Δ H v a p for that substance, you can predict the boiling point at another pressure by plugging in values for P 1 and T 1 (the normal boiling point), P 2 (the pressure you are interested in), and Δ H v a p, the enthalpy of vaporization …
WebThe normal boiling point of a liquid is defined as its boiling point when surrounding pressure is equal to 1 atm (101.3 kPa). Figure 10.24 shows the variation in vapor pressure with temperature for several different substances. Considering the definition of boiling point, these curves may be seen as depicting the dependence of a liquid’s ...
