Unit 1 What is Matter?

Color

Mass

Weight

Volume

Liters (L) and milliliters (mL)

Kilograms (kg) and grams (g)

Meters (m) and centimeters (cm)

Newtons (N) and joules (J)

Mass is measured in kilograms (kg).

Weight is a measure of gravitational force.

Weight is measured in newtons (N).

Mass is measured in liters (L).

Objects with greater mass have greater inertia.

Objects with less mass have greater inertia.

Mass and inertia are unrelated.

Inertia only depends on the shape of the object.

Solubility

Ductility

Flammability

Malleability

Thermal conductivity

Chemical reactivity

Ability to rust

Ability to burn

D = m/V

D = V/m

D = m + V

D = m - V

Lead (solid)

Mercury (liquid)

Silver (solid)

Zinc (solid)

Melting of a popsicle

Rusting of iron

Crushing an aluminum can

Burning wood

Chemical properties can be observed without changing the substance's identity.

Physical properties are more difficult to observe than chemical properties.

Characteristic properties are most useful in identifying a substance.

Physical properties always involve a chemical reaction.

Change in color

Melting of ice

Breaking a stick

Dissolving sugar in water

They change the identity of the matter involved.

They can be easily reversed.

They do not change the composition of a substance.

They often produce new substances.
