As a substance is HEATED its VOLUME...

Back

increases.

Front

Water has a density of

Back

1.0 grams/cm³.

Front

A measure of the gravitational force exerted on an object is called

Back

weight.

Front

What is the formula for density?

Back

Density = mass/volume (m/v).

Front

What happens to the density of most substances when they are heated?

Back

It decreases.

Front

What is the relationship between density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in.

Front

What is the unit of density commonly used in science?

Back

grams per cubic centimeter (g/cm³).

Front

If an object has a mass of 10 grams and a volume of 2 cm³, what is its density?

Back

Density = 10g / 2cm³ = 5 g/cm³.

Front

What does it mean if an object is buoyant?

Back

It can float in a fluid.
