Now run this simulation e that demonstrates the properties of gases. The simulation shows a container with a lid on top. The lid can be opened and closed by dragging it left and right. On the left side of the container is a yellow

handle. Drag this handle right or left to decrease or increase the volume of the container. On the top right of the

container are a thermometer and a pressure gauge. Follow these steps to use the simulation, and then answer the

question that follows.

1. Reduce the container to its least volume by dragging the yellow handle as far right as you can.

2. In the Gas in Chamber menu, add 80 molecules of heavy species to the container.

3. In the Constant Parameter menu, select Pressure.

4. Increase the number of heavy species molecules to 200.

What do you observe when the molecules are increased from 80 to 200 at constant pressure?
