How Gases Behave

Each of these flasks contains the same number of molecules. In which container is the pressure highest?

• Flask 1
• Flask 2
• Flask 3
• Flask 4

Which of the following changes to a system WILL NOT result in an increase in pressure?

• Increasing the volume of the container
• Decreasing the volume of the container
• Adding more gas molecules
• Raising the temperature

Gas pressure is caused by:

• barometers
• gas molecules hitting other gas molecules
• gas molecules condensing to a liquid
• gas molecules colliding with surfaces

In which flask will the molecules be moving slowest?

• Flask 1
• Flask 2
• Flask 3
• Flask 4
