In which state are the particle(s) is able to be compressed?

• solid

• liquid

• gas

• liquids and gases

• all of them

How are pressure and volume related?

• Directly
• Indirectly
• They aren't related

In a hot air balloon, you turn on the flame, volume increases. What Gas Law is this?

• Charles's Law

• Boyle's Law

• Gay Lussac's Law

According to Boyle's law, at constant temperature, as the pressure of a given sample of gas is increased, the volume will –

• Increase
• Decrease
• Remains the same

What happens to the average kinetic energy of matter when it is heated?

• It increases
• It decreases 
• It doesn't change
• It cannot be determined

Gas molecules can easily be compressed  because ___________. 

• gas molecules are soft
• gas molecules are far apart
• gas molecules follow the shape of the container

How do gas molecules move? 

• in an orderly fashion 
• constantly and randomly
• in straight line paths
• in a circular motion

Collisions between gas particles are said to be "elastic" because _________________________.

• they have a stretchy waistband
• kinetic energy is lost between particles
• kinetic energy is not lost between particles and is instead transferred
• particles move in a straight line
