Density and Buoyancy

100

What is buoyancy?

the tendency to rise or float in water or air.

OR: the upward supportive force of an object in a fluid.

200

What is buoyant force?

The upward force exerted on objects submerged in fluids

300

What is density?

The amount of mass in a certain unit volume of a substance

400

What is mass?

The amount of matter in a substance

500

What is volume?

A Measurement of the amount of space occupied by the substance

Density Equations

100

What is the equation for density?

Density = Mass/volume

Fluids

100

What is a fluid?

Any substance that flows

200

What is a solid?

The state of matter of a substance that has a definite shape and volume

300

What is a liquid?

The state of matter of a substance that has a definite volume but no definite shape

400

What is a gas?

The state of matter of a substance that has neither a definite shape nor a definite volume

500

Give the 5 major points of the particle theory

1) All matter is made up of very small particles

2) All particles in a pure substance are the same

3) There is space between the particles

4) Particles are always moving

5) The particles in a substance are attracted to each other

Density and Buoyancy Continued

100

What is weight?

The force of a gravity exerted on an object

200

What is capacity?

The greatest amount of fluid that a container can hold

300

What is displacement?

To take the place of something else.

400

What is the Archimedes Principle?

The buoyant force acting on an object equals the weight of the fluid displaced by the object

500

What determines if an object floats or sinks?

If the buoyant force is stronger than the force of gravity, the object will float.

If the force of gravity is stronger than the buoyant force, the object will sink.
