Physical Properties

Back

Characteristics we can observe or measure without changing the chemical composition of the particles in the sample.

Front

Composition

Back

What the particles in the sample consist of.

Front

Mass

Back

The amount of matter in a sample; depends on types and quantity of atoms.

Front

Volume

Back

The amount of space something takes up.

Front

Density (mathematical definition)

Back

The mass of a 1 mL (1 cm³) sample.

Front

Density (description)

Back

How closely packed the particles in a sample are.

Front

Formula to Calculate Density

Back

Divide mass (g) by volume (either mL or cm3) - the answer is the mass of 1 mL (1 cm3).

Front

Temperature

Back

A measure of the amount of motion the particles have.

Front

Pressure

Back
