a single kind of matter that has a specific set of properties
(each different element is a pure substance)

chemistry

study of the properties of matter and how matter changes

properties

characteristics or traits of a substance that help to identify or classify it

physical properties

characteristic that can be observed/measured without changing a material chemically
examples: mass, volume, density, state, texture, color, hardness, melting point, boiling point

chemical properties

characteristic that can only be observed/measured during a chemical reaction
examples: reactivity, flammability, new substance, heat/light released, color change, odor change, smoke

physical change

changes the form or appearance of matter but does not make any new substances

chemical change

change in matter that produces one or more new substances

solid

state of matter that has a definite shape and volume

liquid

state of matter that has a definite volume but no definite shape

gas

state of matter that has no definite shape or volume

melting point

unique temperature that a substance starts to melt

boiling point

unique temperature that a substance starts to boil

heat energy

is a form of energy that moves from warmer objects to less warm objects

condensation

the change of state from a gas to a liquid

vaporization

the change of state from a liquid to a gas

sublimation

the change of state from a solid directly to a gas

melting

the change of state from a solid to a liquid

freezing

the change of state from a liquid to a solid

evaporation
