PHET: Gas Properties Simulation

Now that there is matter in the box, there will also be a temperature and a pressure. Look at the pressure gauge and the thermometer. Record the temperature and pressure below.

What happened to the pressure in the box when you raised the temperature?

What happened to the pressure of the gas when you decreased the volume of the box?

What happens to the gas molecules? Why does this happen?

As the gas particles leave the box, what happens to the temperature and pressure in the box?

What happens to the pressure when there are more particles in the box?

On the right side of the screen, click the box for the “Collision Counter”. Click the play button to record the number of times the gas particles collide with the wall. Number of Collisions ________________

What relationship is there between pressure and the amount gas in a container?

Set the number of blue to 10. Describe the motion of the particles. (Are they moving fast or slow? Are they all clumped together or spread out?)
