True or False: Gases don't weigh ANYTHING
False
The particle model of matter states that heating matter causes particles to move ___________.
Faster
When water vapor turns into liquid water on a cold surface, it’s going through this process.
Condensation
This vocabulary word describes the change from a liquid to a gas that can happen at the surface of the liquid.
Evaporation
Orange juice, syrup, milk, and lemonade are all examples of?
Liquids
Ice, Chocolate, Wax, and Cheese all ____________ when heat is applied.
Melt
The particle model of matter states that cooling matter causes particles to move ___________.
Slower
This is the term for the amount of space an object or substance occupies.
Volume
Matter is anything that has (1)__________ and takes up (2) __________
(1) Mass (2) Space
This tool measures the temperature of something
A Thermometer
Liquid and Gas
As particles move faster, the attractive forces between them gets (1)_________(stronger or weaker) and the space between them (2) ____________(increases or decreases).
(1) weaken (2) increases
This term describes the amount of matter contained within a specific volume.
HINT: two things can be the same size, but this could be different (a bowling ball vs. a soccer ball)
Density
When a thermometer is put into hot water, the liquid in the tube goes (1) ________ because it is (2) __________.
(1) Up (2) Expanding
Sidewalks, railway tracks, and bridges all are designed with spaces in between to allow for (1) ____________ and (2)____________.
(1) Expansion (2) Contraction
This is the term for an educated guess about what will happen in an experiment.
Hypothesis
As particles slow down, their attractive forces (1) __________(increases/decreases) and the space between them (2)___________(increase/decrease).
(1) Increases (2) Decreases

(1) Dense (2) Floats
The process where a solid changes directly into a gas without becoming a liquid first. HINT: This happens when dry ice is exposed to room temperature air.
Sublimation
When Ice melts, the (1)___________ changes, but the (2)_________ stays the same.
(1) Volume (2) Mass
What would happen if Ice was MORE DENSE than liquid water?
Ice would sink, animals in the lake or river would die in the winter
