The vapor pressures of various compounds are measured using a device which contains a large chamber into which the solid or liquid is placed. The device is sealed and a pressure gauge measures the pressure as equilibrium is reached in the chamber.
Figure 1. Vapor pressure apparatus.
Various samples are placed inside the device and measured and the following results are obtained:
