Phases of Matter
A chair is an example of what phase of matter?
solid
If you add energy to a liquid, it becomes a gas. What phase change it this?
evaporation/ vaporization
Gravel and water
mixture
salt
solute
magnetic, shiny, maleable, phase of matter, boiling point, ect...
Steam is an example of what state of matter?
gas
If you take away a lot of energy very quickly from a gas, it becomes a solid. What phase change is this?
deposition
marshmallows and cereal in Lucky Charms cereal
mixture
water
solvent
give an example of a chemical property
flamability, oxidization, rusting, reacting with substances.
Volume is the amount of _____________ that matter takes up.
space
In the phase change melting, is energy being added or taken away?
added
Kool-Aid mix and water
solution
liquid in which a material is dissolved
solvent
What is the difference between a physical property and a chemical property
a physical property has to do with a substances physical characteristics. A chemical property has to do with how it interacts and chemically changes with other substances
The state in which molecules move the slowest
solid
Which three phase changes require you to take away energy?
deposition, condensation, and freezing
Ovaltine (chocolate drink mix) and milk
solution
the material that is dissolved in a liquid
solute
give 2 examples of physical changes
dissolving, cutting, folding, shape changes, phase changes
The state in which molecules move the fastest
gas
list the 6 phase changes and what phases of matter are changing for each.
condensation= gas to liquid
evaporation= liquid to gas
sublimation= solid to gas
deposition= gas to solid
freezing and melting too
Are all mixtures solutions?
No, but all solutions are mixtures (they are a special type of mixture)
The more (1) _____________ dissolved in a given amount of (2) ______________ , the more concentrated the solution is.
(1) solute
(2) solvent
Give 2 examples of chemical changes
forming a precipitate, fizzing, rusting, changing phase with out energy change
