The upward force that fluids exert on all matter.

• Pascal

• Fluid

• Atmospheric

• Buoyant

Fluid pressure increases as depth increases.

• True

• False

When heat is added to a sample of gas sealed in a container, which of the following will most likely happen?

• The temperature of gas will increase because the gas molecules will move much more slowly.
• The temperature of gas will decrease because the gas molecules will move faster
• The temperature of gas will increase because the gas molecules will move faster. 
• Temperature of gas will decrease because the gas molecules will stop moving

What is a change that will NOT affect the pressure in a container?

• weight of fluid

• heating or cooling of fluid

• volume of fluid

• material of the container

If the pressure in a container decreases, what happens to the pressure? It...

• decreases

• increases

• stays the same

• increases then quickly decreases

Buoyancy is:

• When an object sinks in liquid

• The ability to float in some liquid material

What does buoyancy depend on?

• The size of an object.

• The color of an object.

• The weight of an object.

• None of the above.

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

What is the equation used to calculate pressure?

• pressure= force/mass
• pressure =mass/volume
• pressure=area/force
• pressure=force/area
