1. True: True or False: heat is a form of energy
2. 0 degrees Celsius: The freezing point of water on the Celsius scale is...
3. 0 K: The absolute zero temperature on the Kelvin scale
4. -273 degrees C: The lowest temperature possible in nature (in degrees C) is
5. stay the same: If molecules in a gas sample moved so they completely missed
each other, the gas's temperature would
6. False: True or false: Temperature is a form of energy
7. 78 degrees f: Room temperature in Fahrenheit
8. 300 K: Room temperature on the Kelvin scale is about
9. 32 degrees F: freezing point of water on the Fahrenheit scale
10. -47.2 degrees F: The temperature in January in Winnipeg, Manitoba, has been
known to go down to -44 degrees C. What is this temperature on the Fahrenheit
scale? Round your answer to 1 decimal place.
11. 210.2 K: The lowest temperature ever recorded in the United States is -81
degrees F. What is this temperature in kelvins? Round your answer to 1 decimal
place
12. gases and liquids: Energy transfer by convection is primarily restricted to
13. Conductor, insulator: Your feet feel warmer on a rug than on tile because tile
is a better , while the rug is a better
14. 2nd law of thermodynamicsf: Entropy is closely related to the
15. increases: As a system becomes more disordered, entropy
16. more entropy: Systems that are left alone, tend to move toward a state of
17. Convection: is heat transferred through the mass motion of a sub-
stance.
18. radiation: The earth receives about 1.7 x 10^17 J of energy from the sun each
second through a process called
19. conservation of energy: The first law of thermodynamics is a restatement of
the
20. 0.0042 N: A positive charge of 86 nano-Coulombs is 13 cm from a charge 92
nano-Coulombs. The force on one of the charges due to the other charge is
Newtons. Round your answer to 4 decimal places.
21. 1 x 10^-9: 1 Nanocolumb = ? Columbs
22. -2.4 N: A positive charge of 0.00016 C is 24 m from a negative charge of 0.00096
C. What is the force of one of the charges due to the other charge in units of
Newtons? Round to one decimal place.
23. moves from your finger to the ice: When you touch a cold piece of ice with
your finger, energy
