Introduction to Gases/Boyle's Law

What happened to the volume between the two steps?

• volume increased
• volume decreased
• volume stayed the same

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

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

What causes pressure?

• The walls of the container
• The vacuum in the container
• The collisions of the particles
• Atmospheric pressure acting on the outside walls

True or False: Gases can be compressed. 

• True
• False

When Pressure increases then the Volume must...

• Increase
• decrease

When Volume increases then Pressure 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

What is the formula for Boyle's Law?

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

A gas at a volume of 4 liters is at a pressure of 8 Pa. The volume is changed to 16 Liters, what must the new pressure be?

• 1 Pa
• 12 Pa
• 10 Pa
• 2 Pa
