Chapter 4 Review: Buoyancy and Pressure

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

• increases

• decreases

• stays the same

What is pressure?

• The amount of force exerted on a surface

• The surface area of an object

• The weight of an object

A fluid can be...

• a gas
• a liquid
• a liquid or a gas
• a solid

When you increase your altitude, the atmospheric pressure

• increases

• decreases

• stays the same

Where is the air pressure the greatest?

• 1
• 2
• 3
• 4

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

• More

• Less

• The same

Which of the statements is true?

• The bottom of the boot exerts more pressure than the high-heeled shoe as a result of an increase in surface area.
• The bottom of the high-heeled shoe exerts more pressure than the boot as a result of an decrease in surface area.
• The bottom of the high-heeled shoe exerts the same pressure as the bottom of the boot.

When force increases...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases

When area increases...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases

Any substance that can easily flows and therefore can easily change shape.

• Fluid

• Liquid

• Gas

• Solid
