a state of matter in which molecules vibrate in fixed positions

Solid

100

Describe how gas particles behave

They are very far apart and move in random motions

100

to change from a solid to liquid state  

Melt

100
As a solid becomes a liquid, does the thermal energy increase or decrease?

Increase

100

Matter can be lost during a phase change.

False - it is not lost, it just changes forms

200

a state of matter in which molecules move freely while remaining in contact

Liquid

200

This state of matter has a fixed volume, but not a fixed shape

Liquid

200

to change from a liquid to solid state

Freeze

200

As a gas becomes a liquid, does the thermal energy increase or decrease?

Decrease

200

There such a thing as "cookie gas".

True

300

a state of matter in which molecules are in constant random motion

Gas

300

Describe the particles of liquid

they are close together, but can slide past each other

300

to change from a liquid to gas state

Evaporate

300

As a liquid becomes a gas, does pressure increase or decrease?

Increase

300

Theoretically, there is such a thing as "liquid fart".

True

400

Give 3 examples of matter

solid, liquid, gas

400

Describe how solid particles behave

They are tightly packed and move very little. 

400

to change from a solid to gas state

Sublimation

400

As a liquid becomes a solid, does pressure increase or decrease?

Decrease

400

Give an example of a substance that is neither liquid nor solid.

gelatin, oobleck, plasma, etc. 

500
Define: Matter

anything that has mass and takes up space

500

________ particles have no fixed shape and no volume.  ________ particles have a fixed shape and a volume. 

Gas, Solid

500

to change from a gas to solid state

Deposition

500

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.

500

b. Liquid Water

c. Gas Water

a. Ice


b. Water


c. Vapor / Steam
