Density and Matter (Dalton)

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in grams per cubic centimeter (g/cm³).

Front

Why do objects float on water?

Back

Objects float on water if they have a density lower than that of water.

Front

What is the density of water?

Back

The density of water is 1.00 g/cm³.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What happens to objects with a density higher than water?

Back

Objects with a density higher than water sink.

Front

What is the unit of measurement for density?

Back

The unit of measurement for density is grams per cubic centimeter (g/cm³).

Front

If an object has a mass of 50g and a volume of 25cm³, what is its density?

Back

Density = 50g / 25cm³ = 2.0 g/cm³.

Front

What is the relationship between mass, volume, and density?

Back

Mass is directly proportional to density and volume; as mass increases, density increases if volume remains constant.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, determined by the object's density compared to the fluid's density.

Front

What is the significance of the density of a substance?

Back

The density of a substance helps determine whether it will float or sink in a fluid.
