Pressure in Fluids

When you increase your altitude, the atmospheric pressure

• increases

• decreases

• stays the same

When you increase your depth under water, the water pressure on your body

• increases

• decreases

• stays the same

Where is the air pressure the greatest?

• 1
• 2
• 3
• 4

Are there more or less atoms at lower altitudes

• more atoms

• less atoms

If an object's surface area is smaller does it create more or less pressure?

• More

• Less

• The same

Why won't you sink in mud if you wear boots?

• Because the surface area is larger creating less pressure.

• Has air in it to keep you floating.

• Because the mud won't want you.

Diagram shows the design of a dam. Why does the thickness of the dam increase with its depth?

• The design of this structure is stronger.

• Water pressure increases with depth.

• The cost of construction is lower.

• Water pressure acts uniformly in all directions.

The figure shows a pond with two fish P and Q.

What is the correct relation of the water pressures on fish P and fish Q?

• Water pressure on fish Q > Water pressure on fish P.

• Water pressure on fish Q < Water pressure on fish P.

• Water pressure on fish Q = Water pressure on fish P.

If the horse reared up on 2 legs what effect would it have on the pressure?

• it will exert half the pressure it did before
• it will exert the same pressure it did before
• it will exert twice the pressure it did before
• it will exert four times the pressure it did before

Where is pressure the greatest on the dam?

• D
• C
• B
• A
