States of Matter
The state of matter depends
on temperature and
pressure

Solid
Molecules are packed
closely together
Liquid
 Molecules can slip by each
other because they have more
energy
Gas
Molecules move freely all
around each other with more
energy
Plasma
 Contains the most energy and occurs at
very high temperatures
 Found in fluorescent lightbulbs, the
atmosphere and lightning strikes, tv tubes

States of Matter
Changes of state
 Requires energy
 Melting point- temp where a solid becomes a liquid
 Boiling point- temp. where a liquid becomes a gas
