Buoyancy of Fluids

Key Term: Buoyancy

Key Concepts: Archimedes’ Principle Why do objects float? How do you determine the pressure a

gas exerts on its container?

Buoyancy of Fluids

Why do you feel lighter in the pool than you do on land? The water in the pool exerts an

upward force on you Buoyancy is a measure of this

upward force

Buoyancy of Fluids A Greek in the 3rd century BC

discovered that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This is called Archimedes' Principle.

Buoyancy of Fluids An example:

A rock weighs 2.25N in air It weighs 1.8N in water The volume of the rock is 45mL The buoyant force of the water on

the rock is .45N (water’s density is 1.0 g/cm3)

In glycerin (density of 1.26 g/cm3), the rock weighs only 1.72N, because the buoyant force is larger.

Buoyancy of Fluids

The buoyant force explains why some objects float and others sink In the previous example, in order to float the

rock, the buoyant force would need to be greater than 2.25N

If the buoyant force is less than the weight, the object sinks

If the buoyant force is greater than the weight, the object floats

Neutral buoyancy occurs when the buoyant force exactly equals the weight of the object

Ex. SCUBA diving

Buoyancy of Fluids

How can steel float? If it were a steel block, it would only

displace its volume in water and the buoyant force would be much less than the weight of the steel

When it is shaped into a boat, then it displaces much more water, making the buoyant force greater than the weight of the boat plus its cargo.

Buoyancy of Fluids

Gas buoyancy Floating hot air balloons displace a large

volume of air. The air weighs more than the entire balloon.

How does this work? Hint: hot air – hot air has a larger volume than an

equal mass of cool air, so it less dense.

Buoyancy of Fluids

Helium Balloons Float because of buoyancy

Helium gas is less dense than air, so it takes up more space

The weight of the air displaced is greater than the total weight of the helium and the rubber balloon
