Name ______________________ Date ____________
Use one to two weeks after the lessons. Keep the notes and the lesson closed.
1. describe / explain
Keep the lesson closed. A fixed amount of gas is kept at the same temperature while the pressure on it is increased. Describe what happens to its volume. Then explain, using particles, why the gas pushes back harder.
2. describe / explain
Keep the lesson closed. A fixed amount of gas is cooled while the pressure on it stays the same. Describe what happens to its volume, and explain why, using particles. Then describe what would happen to the volume of the same gas if, instead, the pressure on it were increased at constant temperature.
