Matter Test

Non-characteristic property of matter

A property that can be used to describe but not identify a substance. (Not unique) Ex: Mass

Characteristic property of matter

A property that identifies a substance (Unique) Ex: Density

Mass

The amount of matter in an object

Units for mass

G, Kg

How do you find the mass of a solid?

Use a balance

How do you find the mass of a liquid?

Mass of beaker with liquid - mass of beaker = mass of liquid

Volume

The amount of space an object occupies

Units for volume

L, cm3, mL

How do you find the volume of a regular shaped object?

Length x Width x Height

How do you find the volume of an irregular shaped object?

Water displacement method

Density

The relationship between mass and volume

Units for density

g/ml, g/cm3

Formula for density

M/V

Formula for volume

DV

Physical property of matter

A characteristic of a substance that can be observed and measured without changing the identity of the substance. Observed using senses, example: color

Physical change of matter

A change that affects one or more physical properties of a substance without changing its composition. Chemical identity remains the same, change in appearance, shape, or size. Example: Cutting, Bending

Chemical property of matter

A substance’s ability to undergo chemical reactions (change) and to form new substances. Examples: Flammability, Ability to rust/tarnish

Chemical change of matter

The process that occurs when one or more substances change into an entirely new substance(s) with different properties. Example: Baking a cake, Iron rusting.

Evidence of a chemcial change

Produces gas (bubbles), Change in color, odor, Temperature change, Difficult or Impossible to reverse
