The Ideal Gas Model Gives Predictions of Gas Behavior
Verify that the Ideal Gas model gives reasonable predictions of gas behavior.
Vary the volume of a gas container and observe the change in the temperature and pressure as a reaction to the volume change. In this experiment, when you suddenly decrease the volume of the syringe, the pressure changes by more than a factor of 2. Why does it do this? When the syringe volume is suddenly cut in half, both the temperature and the pressure go up. After a short time, the temperature approaches room temperature, but the pressure approaches some new, higher value. Why doesn’t the pressure decrease back to its original value as the temperature does?
