• speed up and move closer
• speed up and move farther apart
• slow down and move closer together
• slow down and move farther apart

How do gas molecules move? (more than one answer may be correct)

• in an orderly fashion 
• constantly and randomly

• in straight line paths until they hit the wall of the container or another molecule

• in a circular motion

True or False: Gases can be compressed. 

• True
• False

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

When Pressure increases then the Volume must...

• Increase
• decrease

What type of relationship to pressure and volume have?

• direct
• inverse
• no relationship
• I don't know

Which container will have a LOWER pressure?

• left
• right
• they both have the same pressure
• I don't know

The relationship of which two variables are compared in Boyle's Law?

• pressure & volume
• volume & temperature
• temperature & pressure
• volume & moles (amount of gas)

Which of the following are assumptions of the Kinetic Molecular Theory?

• Temperature of gas molecules is directly proportional to Average Kinetic Energy.

• Energy is not lost when particles collide and collisions are elastic.

• Particles exhibit constant, random, straight-line motion.

• All of the other answer choices are true.

At a constant volume for a sealed gas, as temperature decreases, pressure

• decreases because the particles slow down and hit the inside of the container softer and less often.

• decreases because the particles speed up and hit the inside of the container harder and more often.

• increases because the particles slow down and hit the inside of the container softer and less often.

• increases because the particles speed up and hit the inside of the container harder and more often.
