Gas Volume-Pressure

Lesson Description:

This lab measures the pressure on a gas with changing volume. The volume will be decreased in 5-cc increments from 65 cc, and you will measure the pressure at each volume.

gas law apparatusInitially, the cylinder on the left is filled with the gas. The valve on the right is closed, sealing the cylinder. Then, you turn the handle on top of the cylinder to squeeze the gas to ever smaller volumes and measure the pressure on the gauge to the right at each volume.
