Vocabulary
a state of matter in which molecules vibrate in fixed positions
Solid
Describe how gas particles behave
They are very far apart and move in random motions
to change from a solid to liquid state
Melt
Increase
Matter can be lost during a phase change.
False - it is not lost, it just changes forms
a state of matter in which molecules move freely while remaining in contact
Liquid
This state of matter has a fixed volume, but not a fixed shape
Liquid
to change from a liquid to solid state
Freeze
As a gas becomes a liquid, does the thermal energy increase or decrease?
Decrease
There such a thing as "cookie gas".
True
a state of matter in which molecules are in constant random motion
Gas
Describe the particles of liquid
they are close together, but can slide past each other
to change from a liquid to gas state
Evaporate
As a liquid becomes a gas, does pressure increase or decrease?
Increase
Theoretically, there is such a thing as "liquid fart".
True
Give 3 examples of matter
solid, liquid, gas
Describe how solid particles behave
They are tightly packed and move very little.
to change from a solid to gas state
Sublimation
As a liquid becomes a solid, does pressure increase or decrease?
Decrease
Give an example of a substance that is neither liquid nor solid.
gelatin, oobleck, plasma, etc.
anything that has mass and takes up space
________ particles have no fixed shape and no volume. ________ particles have a fixed shape and a volume.
Gas, Solid
to change from a gas to solid state
Deposition
Explain what happened when we took the can of boiling water and flipped it into the ice cold water. Use the terms thermal energy and pressure in your answer
As the particles rapidly lost thermal energy, it decreased pressure inside of the can, which made it implode because the pressure outside the can became great rapidly.
Name water in all of its states of matter
a. Solid Water
b. Liquid Water
c. Gas Water
b. Water
c. Vapor / Steam
