Matter 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

The upward force exerted by a fluid is called the...

• buoyancy force

• density force

• fluidity force

• normal force

A fluid's resistance to flow is its

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

If an object has a density of 3.6 g/mL and you put it into water (density =1.0g/mL,) will it sink or float?

• sink

• float

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.

 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.

• Bernoulli's Principle

• Pascal's Principle

If you double the size of the larger pad of a hydraulic system, how much less force do you need to apply to the smaller pad to achieve the same result?

• 1/4 the force

• 1/3 the force

• 1/2 the force

• The same amount of force
