At what temperature and what pressure does the Triple Point of Water Occur? 
0.06 atm and 0.01oC
What unique condition defines the "triple point" of a substance?
Solid, Liquid and A gas simultaneously
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
Which phase of matter does this illustration demonstrate?
Gas
Besides temperature, what other major factors determines whether a substance is a solid, liquid, or gas?
Pressure and Time
Which phase of matter does this illustration represent?
Liquid
what is Endothermic
any process in which energy is being added or absorbed
At the triple point of water, which three states of water are present in balance with each other?
Ice, Water and Steam
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)
Which phase of matter does this illustration demonstrate?
Solid
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
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.
Give an example of sublimation.
Dry Ice: Solid carbon dioxide turns into a foggy gas at room temperature. (solid to gas)
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
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.
Does adding gas change the size of gas particles?
No, pressure causes them to get closer together.
As heat and pressure is increased, the particles of a substance will move ______
Faster
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.
