3.3: Properties of Fluids

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

A fluid's resistance to flow is its

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

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

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

 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.

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.

Which box has a higher density?  

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

How do you find the volume of an irregular shaped solid?

• water displacement
• weighing it
• using a balance
• multiplying the length by its sides

The term fluids generally applies to:

• solid and liquid

• liquid and gas

• solid and plasma

• water only
