A beaker of a liquid with a vapour pressure of 350 torr at 50 C is set alongside a beaker of water (Vapour pressure of 23.76 ton) and both are allowed to evaporate. In which liquid does the temperature change at a faster rate? Why At a given temperature, one liquid has a vapour pressure of 40 ton and another measure 420 ton. Which liquid probably has the lower boiling point? Which probably has the lower heat of vaporization?

Important facts :
- The vapour pressure increases non - linearly with temperature.
- A higher vapour pressure means a low boiling Pont.
- A liquid with a a lower vapor pressure has a higher rate of change of temperature.
From the question above we realize that water has a lower vapor pressure hence has a faster change of temperature.
