SPI 0807.9.1 – Recognize that all matter consists of atoms.
SPI 0807.9.6 – Compare the particle arrangement and type of particle motion associated with different states of matter.
SPI 0807.9.8 – Interpret the results of an investigation to determine whether a physical or chemical change has occurred.
Describe three states of matter.
 The ____________of matter are the _______________ forms in which a
Esubstance can exist.
 ___________ is made up of tiny particles called ________ and __________.
 These particles are always in ___________ and are always ___________ into one another.
There Are ___ states of matter:
1.
A _______ is the state of matter that has a _____________ shape & volume.
 The particles in a solid do ____ move fast enough to ______________ the attraction between them.
 Each particle _______________ in place and is _____________ in place by the particles around it.
There Are Two Kinds of Solids:
 ____________________ solids have a very orderly, three-dimensional arrangement of particles.
 ____________________ solids are made of particles that do not have a special arrangement.
2.
__________ is the state of matter that has a definite volume and but takes the __________ of its container.
 The _____________ of a liquid move fast enough to overcome _______ of the attraction between them.
 So, the particles in a liquid ___________ past each other.
Liquids have ____ special properties:
 ___________ _____________ is a force that acts on the particles at the surface of a liquid.

__________________ is a liquid’s resistance to flow.
3.
_______ is the state of matter that has ____ definite shape or volume.
 The particles of a gas move _________ and can break away
_______________ from one another.
 The amount of _________ space between gas particles can __________.
EEnergy is involved in changes of state.
 A _____________ of _____________ is the change of a substance from one
________________ form to another.
Changes of State:
1. Solid to Liquid 4. Gas to Liquid
2. Liquid to Solid 5. Solid to Gas
3. Liquid to Gas
1. ______________ is the change of state from a __________ to a ____________.
 The _________________ a solid changes to a liquid is its ________ point.
 ___________ energy to a substance during a change of state is called an _________________________ change.
2. ______________ is the change of state from ____________ to a ___________.
 The ________________ a liquid changes to a solid is its _________ point.
 ______________ energy from a substance during a change of state is called an ______________________ change.
3. _____________________is the change of state from a liquid to gas.

Evaporation occurs at the ____________ of a liquid that is _________ its boiling point.
 ______________ is the change of a liquid to a gas __________________ the liquid. The temperature a liquid boils is its ____________ point.
4. ____________________ is the change of state from a gas to a liquid. The condensation point is the _____________________ a gas becomes a liquid.
5. ____________________ is the change of state where a solid changes
_________________ into a gas.
There two changes that can happen when a substance loses or gains energy.
 When most substances lose or gain energy, one of ______ things
_____________ to the substance: temperature changes or state changes.
 But the ______________________ of a substance does ________ change during the change of state.
