The force of a gas's outward push divided by the area of the walls of the container is the gas's:

• pressure

• voulume

• temperature

• surface tension

Which factor can affect gas pressure?

• Temperature 
• Volume
• The Amount of Gas
• All of the answers are correct

The greater the speed of gas particles in a container, the:

• greater the pressure
• fewer collisions there will be
• lower the temperature
• lower the pressure

At a constant pressure, if the temperature is increased, what happens to the volume?

• Increases

• decreases

• stays the same

What happened to the volume between the two steps?

• volume increased
• volume decreased
• volume stayed the same

What happened to the pressure between the two steps?

• pressure increased
• pressure decreased
• pressure stayed the same

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
