Gas Laws Review Graphs

This graph is an example of two variables that are:

• directly proportional
• inversely proportional
• Straight line
• No relation

Which best explains why increasing the pressure on a gas decreases the volume of the gas sample?

• Increasing the pressure causes the gas particles to hit the container walls more often.

• Increasing the pressure on a gas sample moves the gas particles closer together.

• Increasing the pressure on a gas sample causes the kinetic energy to increase.

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

IF we are using Boyles' law and our Pressure goes UP, what must our volume do?

• Go UP

• Go DOWN

• Stay the same

• Wrong law.

A gas occupies 4.98 L at 2.6 atm of pressure. What volume does it occupy at 1.8 atm pressure?

• 12.9 L
• 0.72 L
• 7.2 L
• 3.44 L

Boyles Law Tells That

• The More The Volume The Less The Temperature

• The More The Temperature The Less The Pressure

• The More The Volume The More The Pressure

• The More The Pressure The Less The Volume

How do gas molecules move? 

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

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 is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂
