Chapter 13.1 Quiz

The same force is exerted by each of the following. Which exerts the most pressure?

• a. a foot

• b. a large book

• c. a fingertip

• d. the tip of a ball-point pen

What is the formula for pressure?

• Pressure = Area/Force

• Pressure = Force x Area

• Pressure = Force/Area

• Pressure = Area x Force²

What is the unit for pressure?

• Pascal

• Newton

• Joule

• Kilogram

The state of matter that takes the shape of its container is called a(n)

• gas

• solid

• liquid

• plasma

Describe the relationship between atmosphere pressure and altitude.

• pressure decreases with increasing altitude

• pressure increases with increasing altitude

• there is no change in pressure with altitude

What 2 substances do fluids include?

• Gases and Solids

• Solids and Liquids

• Liquids and Gases

• Gases and Plasmas

Why aren't we crushed by atmospheric or water pressure?

• Our bodies are specialized structures that do not respond to pressure changes

• The pressure inside your body balances the air pressure outside

• The pressure outside is too weak to crush us.

Liquids and gases are both considered fluids. Which is the correct arrangement of particles for liquids and gases?

• Gas particles are tightly packed; liquids are free to move all over

• Gas particles are free to move; liquids are free to move but are much closer than gases

• Liquid particles are closely packed and unable to move; gas particles are free to move.

• Liquid particles are free to move; gas particles are closely packed together unable to move apart.

How does fluid pressure change as you move farther down a column of water?

• pressure decreases as you move farther down the column

• fluid pressure if unaffected by depth of water

• there is not a correlation between pressure changes and depth of water column

• pressure increases as you move farther down the column

Why are gases and liquids considered "fluids"

• because they flow

• because they do not flow

• because they are made of matter

• because they can fill up a container.
