04. Fluid Principles and Gas Laws (conceptual)

A unit of pressure is called a

• bernoulli

• pascal

• pound

• meter

One application of Pascal's principle is

• a hydraulic car lift

• the flight of an airplane

• a speedboat's bottom slapping against the waves

• the buoyancy shown by ducks and other waterfowl

Which of the following is true of the buoyant force?

• it acts in the downward direction

• it acts with the force of gravity

• it acts in the upward direction

• ti makes an object feel heavier

What scientific rule states that the buoyant force on an object is equal to the weight of the fluid displaced by the object?

• Archimedes' principle

• Pascal's principle

• Bernoulli's principle

• Newton's third law of motion

A ship stays afloat as long as the buoyant force is

• less than the ship's weight

• equal to the ship's weight

• less than the ship's speed

• greater than the ship's speed

The mass per unit volume of a substance is its

• density

• buoyancy

• weight

• fluid pressure

This principle says that an increase in pressure on a confined fluid is transmitted equally to all parts of the fluid.

• Newton's Principle

• Bernoulli's Principle

• Archimedes' Principle

• Pascal's Principle

This principle states that the faster a fluid moves, the less pressure the fluid exerts.

• Bernoulli's Principle

• Newton's Principle

• Pascal's Principle

• Archimedes' Principle

Which states of matter are fluid?

• solid

• liquid

• gas

• liquid and gas

A student inflates a balloon with helium then places it in the freezer. The student should expect

• the balloon's volume to increase

• the balloon's volume to decrease

• the balloon's moles to increase

• the balloon's moles to decrease
