Density

Front

What is density?

Back

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

Front

How do you calculate density?

Back

Density = Mass / Volume

Front

What is the formula to find the volume of an object?

Back

Volume = Mass / Density

Front

If an object has a mass of 30 g and a volume of 10 cm³, what is its density?

Back

3 g/cm³

Front

What is the unit of density?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or grams per milliliter (g/mL).

Front

How does temperature affect density?

Back

Generally, as temperature increases, density decreases because substances expand when heated.

Front

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

Back

Mass and volume are directly related to density; if mass increases while volume remains constant, density increases.

Front

What is the density of water?

Back

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

Front

How can you determine the volume of an irregular object?

Back

You can determine the volume of an irregular object using the water displacement method.

Front

If an object sinks in water, what can you infer about its density?

Back

If an object sinks in water, its density is greater than that of water (1 g/cm³).
