Measurement of the average energy of motion of the particles in matter
Heat
Transfer of thermal energy from one piece of matter to another
Conduction
Transfer of thermal energy by particles bumping into each other

Most thermometers work because matter ________ when it is heated.
a. disappears
b. collects radiation
c. expands
d. loses mass
C. expands
A thermometer measures the ___________ energy of motion of particles of matter.
a. total
b. long-term
c. solar
d. average
D. average
Two pieces of the same kind of matter have the same temperature. The one with the larger mass has more __________.
a. conduction
b. thermal energy
c. convection
d. solar energy
b. thermal energy
When thermal energy moves from one piece of matter to another, the transfer is called ____________
a. solar energy
b. heat
c. temperature
d. fuel
b. heat
Thermal energy can be transferred by conduction from on piece of matter to another only if the two pieces are _____________.
a. liquids
b. touching
c. solids
d. fuel
b. touching
Convection takes place only in liquids and _____________.
a. gasses
b. energies
c. solids
d. states
a. gasses
Energy that travels from the sun to Earth is being transferred by ___________
a. conduction
b. fuel
c. convection
d. radiation
d. radiation
Does the same amount of water take up the most space as ice, as liquid water, or as water vapor? Why?
It takes up the most space as ice because the particles are tight together and move back and forth around a point.
Would an all metal barn be as warm in the winter and as cool in the summer as an all wood barn? Why or why not?
No because metal is a conductor and wood is an insulator. The wood holds the heat or cool air in the barn.
What type of clothing should you wear to stay warm in cold temperatures? How does it help?
You should wear heavy clothing that will hold the heat in your body such as a hat and gloves where heat escapes
