Question

A syringe at a temperature of \({\rm{2}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\) is filled with liquid ether in such a way that there is no space for any vapour. If the temperature is kept constant and the plunger is withdrawn to create a volume that can be occupied by vapour, what would be the approximate pressure of the vapour produced?

Short answer

The approximate pressure of the vapour produced at \({\rm{2}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\) will be more than \({\rm{450}}\) torr.

Step-by-step solution

Definition of liquid

One of the states of matter is the liquid state. Because the particles in a liquid are free to move, it lacks a defined form even while having a defined volume. Liquids are made up of atoms or molecules joined together by intermolecular connections.

Estimating the approximate pressure of vapour produced

When a liquid is heated in a closed container and the rate of evaporation equals the rate of condensation, the pressure exerted by the vapours of the liquid on the container walls is referred to as the liquid's vapour pressure.

It either boils at \({\rm{3}}{{\rm{6}}^{\rm{o}}}{\rm{C}}\), or at its vapour pressure is around \({\rm{450}}\) torr. Therefore, the vapour pressure at \({\rm{2}}{{\rm{0}}^{\rm{o}}}{\rm{C}}\) will be more than \({\rm{450}}\) torr.
