Front

What is density?

Back

Density is the mass of a substance divided by its volume. It determines whether an object will float or sink in a fluid.

Front

Why do objects float in water?

Back

Objects float in water if their density is less than the density of water.

Front

What is a conductor?

Back

A conductor is a material that allows electricity to easily pass through it.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to pass through it easily.

Front

What happens to water particles when water is cooled?

Back

The particles of water slow down when the water is cooled.

Front

What happens to water particles when water is heated?

Back

The particles of water speed up when the water is heated.

Front

What is the relationship between temperature and particle movement?

Back

As temperature increases, particle movement increases; as temperature decreases, particle movement decreases.

Front

What is the effect of density on gas behavior?

Back

Gases with greater density will settle below gases with lower density.

Front

How does the density of ice compare to liquid water?

Back

Ice is less dense than liquid water, which is why ice floats.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object will float if it displaces a volume of fluid equal to its weight.
