States of Matter Notes
6th Grade - Mrs. DeJong (EWA)

2. Vocabulary
Solid - the state of matter in which the object has both definite shape and definite volume. A solid will not change shape or volume even if it is placed into a different container. Ice is an example of a solid
liquid is the state of matter in which the substance has a definite volume but not a definite shape. A liquid will take the shape of the container it is in, however, the amount of space it takes up will remain the same. Water is an example of a liquid

3. Vocabulary
gas - the state of matter in which a substance has neither a definite shape nor definite volume. A gas takes the shape and the volume of the container it is in. That is to say a gas is unique in the sense that it will expand or contract to fit its container. Water vapor is an example of a gas.
plasma is a state of matter much like a gas in that it does not have definite shape or volume. The plasma tends to have an abundance of free electrons, so it behaves very differently than gases. While plasma is very rare on Earth it makes up well over 90% of the matter in the universe. Stars are examples of plasmas.

4. Vocabulary Freezing is the change of state from a liquid to a solid
Melting is the change of state from a solid to a liquid
Vaporization is the change of state from a liquid to a gas

5. Vocabulary Condensation is the change of state from a gas to a liquid
Sublimation is the change of state from a solid directly into a gas
Deposition is the change of state from a gas directly into a solid

6. Vocabulary
Ionization - the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes
Deionization - a process by which positive ions of a plasma capture a free (energetic) electron and combine with electrons or negative ions to form new neutral atoms (gas). Recombination is an exothermic reaction, meaning heat releasing

7. Constant Motion Atoms are in constant motion (kinetic energy)
The rate at which atoms or molecules moves determines the state of a substance.

8. Changing the temperature
Increasing the temperature makes the particles move more quickly and spread apart.
Decreasing the temperature makes the particles slow down and move closer together.
