Gas Laws and Gas Behavior

How do gas molecules move? 

• in an orderly fashion 
• constantly and randomly
• in curved line paths

• in a circular motion

When volume increases (at a constant temperature) then the pressure must...

• Increase
• decrease

Which container will have a lower pressure?

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

What causes pressure inside the balloon?

• The walls of the container
• The vacuum in the container
• The collisions of the particles with the container

• Atmospheric pressure acting on the outside walls

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

• Volume will increase
• Volume will decrease
• Volume will not change

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

Which equation would you use to solve the following problem:

"A gas occupies 2 L of space at 0 C. What will its volume be at 100 C?"

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• (P₁V₁)/T₁ = (P₂V₂)/T₂

• None of the above

Which equation would you use to solve the following problem:

"The volume of of 300 mL of gas at 1 atm is decreased to 100 mL. What is the new pressure?"

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• (P₁V₁)/T₁ = (P₂V₂)/T₂

• None of the above

Each of the flasks shown above have different volumes (they are different sizes) but the temperature of each flask is the same. In which flask will the pressure be the highest?

• Flask 1

• Flask 2

• Flask 3

• Flask 4

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently
• rubber in the tires reacts with oxygen in the atmosphere
• air molecules speed up and collide with the tire walls more often
• air molecules diffuse rapidly through the walls of the tire.
