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. <em><u>(rephrase this answer in your own words)</u></em>

  • 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

How do forces in nuclear and chemical reactions differ
marusya05 [52]

1) Nuclear reactions involve a change in an atom's nucleus, usually producing a different element. Chemical reactions, on the other hand, involve only a rearrangement of electrons and do not involve changes in the nuclei. ... (3) Rates of chemical reactions are influenced by temperature and catalysts.

Because sucrose is hygroscopic, how should it be properly stored in a cupboard
kirza4 [7]

Sucrose is stored in dry and closed container, sealed properly.

Explanation:

  • Sucrose is nothing but the table sugar which we use daily in our life.
  • Sucrose is formed by the combination of fructose and glucose so, it called a disaccharide because two monosaccharides are converted to form sucrose.
  • It is a hygroscopic substance. The hygroscopic substance is which is easily vulnerable to water absorption. They tend to absorb water if they are being exposed to humid places.
  • Hence, it should be kept in a dry and close container, sealed properly.
