Question
In a closed lab, experiment is conducted by heating of water. When water is heated, the vapour pressure increased slowly then rapidly increases. As the water reaches to its boiling point, i.e. 1000C, the vapour pressure reaches 1 atm. Which of the following functions best describes the increase in vapour pressure as water is heated to its boiling point?

Solution
The correct option is C Exponential
The
following graph shows the boiling point for water as a function of
the external pressure. The line on the graph shows the normal boiling
point for water.
Therefore, the function describes the exponential form in the graph for the increase in vapor pressure as water is heated to its boiling point.
