Density

Front

What is density?

Back

Density is the mass of an object divided by its volume, usually expressed in g/cm³.

Front

How do you calculate density?

Back

Density = Mass / Volume.

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 10g and a volume of 5cm³, what is its density?

Back

Density = 10g / 5cm³ = 2 g/cm³.

Front

What is the relationship between density and buoyancy?

Back

An object will float if its density is less than the density of the fluid it is in.

Front

What tool is used to measure the volume of a liquid?

Back

A graduated cylinder is used to measure the volume of a liquid.

Front

What is the mass of an object if its density is 4 g/cm³ and its volume is 3 cm³?

Back

Mass = Density x Volume = 4 g/cm³ x 3 cm³ = 12g.

Front

What happens to the density of an object if its mass increases while its volume remains the same?

Back

The density of the object increases.

Front

What is the mass of 1 cm³ of water?

Back

1 cm³ of water has a mass of approximately 1g.

Front

What is the least dense object among a rock, a cork, and a fish if the cork is floating?

Back

The cork is the least dense because it is floating at the top of the water.
