Density

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

How do you calculate density?

Back

Density = Mass / Volume.

Front

If an object has a mass of 10g and a volume of 5cm³, what is its density?

Back

2 g/cm³.

Front

What is the unit of measurement for density?

Back

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

Front

What is the density of a substance with a mass of 20g and a volume of 4cm³?

Back

5 g/cm³.

Front

Why is density important in identifying substances?

Back

Density helps to distinguish between different materials, as each substance has a unique density.

Front

What do you need to know to calculate density?

Back

You need to know both the mass and the volume of the object.

Front

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

Back

The object's density is less than the density of water (1 g/cm³).

Front

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

Back

The object's density is greater than the density of water (1 g/cm³).

Front

What is the density of a rock with a mass of 14g and a volume of 2cm³?

Back

7 g/cm³.
