### The Effect of Temperature on the Vapor Pressure of a

The Effect of Temperature on the Vapor Pressure of a Liquid. Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known the vapor pressure at a second temperature can be calculated.

1. Saturation Vapor Pressure i. Saturation Vapor pressure e s The saturation vapor pressure is the partial pressure of the water vapor in equilibrium with a plane surface of pure water. That means that the rate of condensation is equal to the rate of evaporation. e s is a function of temperature alone it doesn’t depend on the vapor content

### Vapor Pressure and Molecular Weight of a Pure Liquid

Vapor Pressure 2 In a vacuum line the vapor pressure of the substance is directly measured by the pressure transducer. In other words the substance comes in direct contact with the pressure measurement device since there is no intervening open end manometer. Therefore most of the vapor is at a different temperature than the liquid.

### Is the vapor pressure of a liquid a linear function of

Jun 20 2012 The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.

### EXPERIMENT 7

The vapor pressure is a very sensitive function of temperature. It does not increase linearly but in fact increases exponentially with temperature. The vapor pressure of a substance roughly doubles for every increase in 10 C Figure 1. When the vapor pressure of the liquid equals the applied pressure the liquid boils. Thus the boiling point

### Vapor Pressure of Furfural

Figure 107. The Vapor Pressure of Furfural as a Function of Temperature. Although the reaction given above calls for a molar hydrogen to furfural ratio of only 2 1 it is recommended to run the process at a ratio between 6 1 and 7 1. This means that in an atmospheric process the furfural in the vaporizer should have a temperature of 104 C as
