200
what is a solid
matter that has a definite shape and volume
200
what is temperature
the kinetic energy of the individual particles
200
what is boiling
the change from a liquid to a gas
200

the change from a solid directly to a gas
200

What unique condition defines the "triple point" of a substance?

Solid, Liquid and A gas simultaneously

300
what is a liquid
matter that has a definite shape and volume
300
what is heat
the movement of thermal energy form high to low temp.
300
what is melting
a solid to a liquid
300
what is deposition
the changing of a gas directly to a solid
300

How does adding heat (thermal energy) generally affect the particles of a solid as it changes into a liquid?

They begin to move faster and further away from one another 

400
what is a gas
matter with no definite shape and no definite volume
400

Which phase of matter does this illustration demonstrate?

Gas

400
what is condensation
the change from a gas to a liquid
400
what is Exothermic
any process that releases energy
400

Besides temperature, what other major factors determines whether a substance is a solid, liquid, or gas?

Pressure and Time

500
what is a plasma
an ionized, electrically charged gas
500

Which phase of matter does this illustration represent?

Liquid

500
what is vaporization
the change from a liquid to a gas
500

what is Endothermic

any process in which energy is being added or absorbed

500

At the triple point of water, which three states of water are present in balance with each other?

Ice, Water and Steam

600

Give an example of Deposition.

Frost formation: Water vapor in freezing air turns directly into ice crystals on cold grass, leaves, or car windows.  (Gas to a solid)

600

Which phase of matter does this illustration demonstrate?

Solid

600

As the ___________ increases, particles move faster and the average distance between them increases. Fill in the blank, what causes this to happen?

Temperature, adding heat

600

SCUBA divers carry large quantities of oxygen in specialized tanks to allow them to breathe underwater. How can a large quantity of gas be stored in a relatively small tank? 

By applying pressure, pressure pushes gas particles closer together allowing more to fit into a smaller space. 

600

Give an example of sublimation.

Dry Ice: Solid carbon dioxide turns into a foggy gas at room temperature. (solid to gas)

700

Look at the portion of the graph circled in RED, what does it tell you about the temperature and the time?

They are both Increasing

700

Look at the portion of the graph circled in RED, what does it tell you about the temperature and the time?

Time is increasing (20 mins to 30 mins), temperature (55) remains the same.

700

Does adding gas change the size of gas particles?

No, pressure causes them to get closer together. 

700

As heat and pressure is increased, the particles of a substance will move ______

Faster

700

Watching an ice cube melt in the sun. Describe what is happening to the particles. Do they gain or lose energy and will they undergo a phase change?

They move faster. They gain energy (heat), the ice will melt.
