Fluids

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.

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.

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

• fluid

• pressure

• buoyant force

• normal force

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

Which principle do airplanes take advantage of to fly?

• Archimedes' 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

When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This fact is called________.

• Pascal's Principle

• Newton's Principle

• Archimedes' Principle

• Bernoulli's Principle

Any substance that can easily flows and therefore can easily change shape.

• Fluid

• Liquid

• Gas

• Solid
