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) or kilograms per liter (kg/L).

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What units are used to measure mass?

Back

Mass is measured in grams (g), kilograms (kg), and milligrams (mg).

Front

What units are used to measure volume?

Back

Volume is measured in cubic centimeters (cm³), milliliters (mL), liters (L), and cubic meters (m³).

What happens to an object with a density less than water?

Back

An object with a density less than water will float.

Front

What happens to an object with a density greater than water?

Back

An object with a density greater than water will sink.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

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

Back

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

Front

What is an example of a substance that floats on water?

Back

Oil is an example of a substance that floats on water because it is less dense.

Front

What is an example of a substance that sinks in water?

Back

A rock is an example of a substance that sinks in water because it is more dense.
