Properties of Matter
Physical and Chemical Properties
More Notes and Vocabulary…
Describing Matter
• Physical Property – characteristic of a material
that you can observe without changing the
substance
– Example: color, size, shape, density, melting point,
boiling point, texture, mass, volume
– Color
Shape
Texture
• Chemical Property – characteristic of a
substance that indicates whether it can
undergo a certain chemical change
– Example: flammable, combustible, may react to
light
Physical and Chemical Changes
• Physical Change – a change in size, shape or
state of matter; substance DOES NOT change
identity when it undergoes physical change.
– Example: melting ice, cutting paper, breaking glass
Chemical Changes
• Chemical Change – a change in one substance
to another substance
– Example: fireworks exploding, leaf changing color,
cake baking, rusting metal
Law of Conservation of Mass
• Law of Conservation of Mass – says that the
mass of ALL substances present before a
chemical change equals mass of ALL
substances after the change.
