Physical Science - Matter and Density

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

What happens to the density of an object when it is cut into smaller pieces?

Back

The density remains the same regardless of the size of the pieces.

Front

Why does ice float in water?

Back

Ice floats in water because it is less dense than liquid water.

Front

What is the mass of an empty beaker if it weighs 60 grams and weighs 200 grams when filled with mercury?

Back

The mass of the mercury is 140 grams.

Front

What is the relationship between mass and volume in determining density?

Back

Density increases with mass if the volume remains constant.

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 density of 10 g/cm³ and a volume of 2 cm³, what is its mass?

Back

Mass = Density x Volume = 10 g/cm³ x 2 cm³ = 20 grams.

Front

What is the principle of buoyancy?

Back

The principle of buoyancy states that an object will float if it is less dense than the fluid it is in.
