Review Pressure

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

How do you Calculate Pressure

• Force(N)/Area(m²)

• Force(kg)/Area(mi²)

• Area(m²)/Force(N)

What pressure does a 4000N horse exert on the ground if each foot is 10cm²?

• 40 N/cm²
• 100 N/cm²
• 400 N/cm²
• 10 N/cm²

The pressure resulting from a force of 50 N exerted over an area of 5 m² is

• 10 N
• 0.1 N
• 10 N/m2
• 0.1 Pa

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?

• The pressure will increase

• The pressure will decrease

We can increase the pressure of a gas by:

• Not changing the temperature of the gas

• Decreasing the temperature of the gas

• Increasing the temperature of the gas

How do gas molecules move? 

• in an orderly fashion 
• constantly and randomly
• in a circular motion

Gas pressure is caused by

• Gas molecules colliding with each other and walls of container

• Gas molecules not moving

Which container will have a lower pressure?

• left
• right
• they both have the same pressure

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
