Matter
Mass
the amount of matter an object contains

States of Matter
Solid – definite shape definite volume Particles of a solid
are packed close together and the motion seems to be a vibration.

States of Matter
Liquid - no definite shape definite volume Particles of a liquid
bump into each other; they push the particles farther apart and move past them. This causes the "flow" of a liquid.

States of Matter Gas –
no definite shape
no definite volume
The particles collide with enough force to push the particles so far apart that they escape the attraction of the surrounding particles.
high compressibility

4th State of Matter?Plasma
Closely related to gases
Particles are neither molecules or atoms, but rather electrons and positive ions
Formed at very high temperatures (high enough to ionize the atoms)
Move freely like the particles of a gas
ExamplesStars, comets, and aurora borealis

Names for phase changes Melting - Solid changes to
Liquid
Freezing - Liquid changes to Solid
Sublimation - Solid changes to Gas
Deposition - Gas changes to Solid
Vaporization - Liquid changes to Gas Evaporation - vaporization
that takes place at the surface of a liquid.
Condensation - Gas to Liquid

Kinetic Energy
As matter moves from the (solid → liquid → gas) its kinetic energy increases
Kinetic Energy Law Matter is made up of small particles (atoms,
molecules, ions) These particles are in constant random
motion These particles collide with themselves and
the wall of their container What happens as temperature is
increased?
