Demo 16-04 Pressure vs. Volume Simulation

This demonstration shows a model that uses small metal balls to simulate gas molecules. As the volume of the container decreases and the average speed of the "molecules" increases, the rate at which the "molecules" strike the sides of the container increases, so the "pressure" in the container increases, as shown in the video. The apparatus, shown in Figure 1, is available commercially from a number of scientific supply houses
