Physical Science Unit 3 Test Review

The ability of a fluid to exert an upward force of an object immersed in it is

• viscosity.
• buoyancy.
• vaporization.
• thermal expansion.

According to Pascal, pressure applied to a fluid

• increases as it moves through the fluid.
• decreases as it moves through the fluid.
• fluctuates as it is transmitted throughout the fluid.
• is transmitted unchanged throughout the fluid.

A fluid's resistance to flow is its

• viscosity.
• density.
• pressure.
• buoyancy.

As the velocity of the fluid increases, the pressure exerted by the fluid decreases is stated in 

• Archimedes' principle.
• Bernoulli's principle.
• Charles' law.
• Pascal's principle.

 The buoyant force on an object is equal to the weight of the fluid displaced by the object is stated in 

• Pascal's principle.
• Archimedes' principle.
• Boyle's law.
• Bernoulli's principle.

Which box has a higher density?  

• Box A
• Box B
• cannot be determined
• they are the same

If an object sinks in a fluid, _____.

• the density of the fluid is greater than the density of the object
• the density of the fluid is less than the density of the object
• the density of the fluid is equal to the density of the object
• density has nothing to do with whether an object sinks or floats, only which state of matter the object is

What do we call the the amount of force exerted on a certain area?

• fluid

• pressure

• buoyant force

• normal force

Car brakes and car jacks are examples of

• hydraulic systems
• archimedes' principle
• atmospheric pressure
• buoyancy

Which is a quality that only gasses display

• Spread out to fill all available space
• Take the shape of their container
• Can't be compressed
• All of these
