Question

Directions:

Answer 1

Answer:

1.

a) F; Insulator

b) F; are always moving

c) T, T, T

d) T, T, T

2. b; firm and not readily movable

3. a; occupied

4.

Temperature: =

Thermal energy: <

sentences: 14, 15

5. cool

sentence: 21

6. radiation; the heat from the heating coil is radiated to the cake and causes it to rise

(though if you really want to sound smart you can explain how all of them are used) (radiation: heating coil; convection: hot air circulating in the oven; conduction: cake pan to cake)

7. conduction; the heat from oatmeal is transferred to the bowl through contact

8. convection; the air is circulated due to uneven heating (of the earth by the sun)

9. (rephrase this answer in your own words)

• jacket: Insulator; prevents heat loss from the cold outside air
• sleeping bag: insulator; keeps me warm at night while it is cold outside of it
• cooking pans: conductor; heat from the flame (of a stove) is transferred to the pan to cook food; it would be very inefficient to use an insulator for something that needs to transfer heat

• (metal) tent stakes: get cold fairly quickly in the cold air, if they were insulators then they would not change in temperature so quickly

10. as the wax melts and turns to liquid the particles drastically speed up to the point where they begin to flow around each other
