Gases and Gas Laws

A student inflates a balloon with helium then places it in the freezer. The student should expect

• the balloon's volume to increase

• the balloon's volume to decrease

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change
• Balloon freezes to death

Which of the following would increase the (gas) pressure of a system?

• Increase the Temperature
• Pump in more gas
• Decrease the volume
• All of these

Boyle's law :  The pressure and volume of a gas show a _____ relationship. 

• No relationship 
• Direct 
• Inverse 
• Equal

You have a gas that has a pressure of 2 ATM and a volume of 10L.  What would be the new volume if the pressure was changed to 1 ATM?

• 5 L
• 20 L
• It would stay at 10L
• 1 L

What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase

• Decrease

• Nothing

• Explosion!

When the temperature of matter increases the particles...

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

What does Boyle's law relate to?

• Temperature and Volume
• Volume and Pressure
• Temperature and Pressure

What is the formula for Boyle's Law?

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

Which container will have a lower pressure?

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