Gas Laws involve what four concepts?

• Solid, Liquid, Gas, Plasma

• Speed, Velocity, Acceleration, Deceleration

• Elements, Compounds, Mixtures, Molecules

• Pressure, Temperature, Volume, Number of Moles

Charles' Law States...

• As Pressure goes up volume goes down
• As Pressure goes up temperature goes up
• As Volume goes up temperature goes up 
• As Pressure goes down volume goes down 

Whose law states that as pressure goes up, volume goes down?

• Charles 
• Boyle
• Aglow
• Mazias 

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 type of relationship is Charles' Law?

• Inverse
• Direct
• Not enough information
• #goals

What is the formula for Boyle's Law?

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

What type of relationship to pressure and volume have?

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

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

• P1/T1 = P2/T2
• P1V1 = P2V2
• V1/n1 = V2/n2
• PV = nRT

A sample of a gas has a volume of 852 mL at 298 K. What temperature is necessary for the gas to have a volume of 945 mL?

• Pt = P1 + P2 + P3 + ...
• P1V1 = P2V2
• V1/T1 = V2/T2
• P1V1/T1 = P2V2/T2

If a nitrogen gas occupies a volume of 500 ml at a pressure of 0.971atm. What volume will the gas occupy at a pressure of 1.50 atm?  

• P1V1 = P2V2
• PV = nRT
• P1/T1 = P2/T2
• V1/n1 = V2/n2
