3. Frost forming from water vapor in the air = “deposition”

4. Is this a snowflake forming by deposition,
or a snowflake melting, played in reverse?

12. Celsius vs. Fahrenheit Graphing Activity
(part of your “lab” grade)
Freezing point of water = 32oF = 0oC
Boiling point of water = 212oF = 100oC
Room temperature = 70oF. What’s that in Celsius?
Human body temperature = 98.6oF. What’s that in Celsius?
Absolute zero = -273oC. What’s that in Fahrenheit?
Boiling point of liquid nitrogen = -196oC = ???oF
Equation for a straight line: y = mx + b (where m = Dy/Dx)
1. Graph the freezing point and boiling point of water on graph paper, algebra-style, w/origin in middle of paper. Connect the dots.
2. Use math to determine the equation(s) for your line.
(C=f(F) & then F = f(C))

13. Relative # of molecules

14. 13.1 Vocabulary Quiz
crushing force exerted by the earth’s air squeezing you = atmospheric pressure
device used to measure pressure = barometer
empty space = vacuum
energy of motion = kinetic energy
force/area exerted by any freely-flying molecules = gas pressure
model of matter where we imagine it to be made of moving particles = kinetic theory
760 mm Hg = standard atmosphere (atm)
1/100,000 of 760 mm Hg = Pascal (Pa)

15. 13.2 Vocabulary Quiz
boiling point of water at sea level = normal boiling point
liquid becoming a gas = vaporization
pressure exerted by a gaseous material when in equilibrium with a neighboring body of liquid of the same material [HARD] =
vapor pressure
temperature at which vapor pressure of the material in a liquid equals the surrounding atmospheric pressure [HARD] =
boiling point
vaporization at the surface of a non-boiling liquid = evaporation

16. 13.3 Vocabulary Quiz
different molecular forms of the same element, such as diamond and graphite or oxygen gas and ozone =
allotropes
non-crystalline solid = amorphous solid
smallest possible amount of a crystal that has the same shape as the crystal as a whole =
unit cell
solid in which particles are arranged in an orderly, repeating pattern = crystal
temperature at which a solid changes to a liquid = melting point
transparent, amorphous solid formed by melting and non-crystalline solidification =
glass
