Summary of Chemistry - Gases - PHET Simulation (temperature, pressure, volume, amount)

00:00:00 - 00:00:00

In the video, Mr. Crew and Mr. Collier demonstrate the use of a gas simulation and its manipulation of various variables. They learn that an addition of gas particles increases pressure, using two different sized gas particles results in equal pressure, cutting the room in half increases pressure, while holding volume constant while increasing temperature increases pressure too. They also observed that when they keep pressure constant and cool the gas, the volume decreases. The simulation proved useful in understanding how changes in different variables affect a gas system.

• 00:00:00 In this section, Mr. Crew and Mr. Collier demonstrate how to use the gas simulation and the various ways to manipulate different variables. They start by observing how adding more gas particles increases the pressure and then conclude that adding an equal amount of two different sized gas particles results in equal pressure. They then manipulate the volume and observe that cutting the room in half increases pressure, and holding the volume constant while increasing the temperature increases pressure as well. Lastly, they observe that when they keep the pressure constant and cool the gas, the volume decreases. Overall, the simulation can be useful for understanding how changes to different variables affect a gas system.
