|
Most thermometers work because matter ________ when it is heated.
a. disappears b. collects radiation c. expands d. loses mass |
C. expands
|
|

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
