Lesson 202 Energy Transfer

Question 1

What are the four processes by which heat energy is transferred in the atmosphere?
(Heat exchange or transfer of mass)

Answer 1

Radiation (heat exchange)
Conduction (heat exchange)
Convection (mass transfer)
Advection (mass transfer)

Question 2

In the following list, state whether the process absorbs or releases latent heat during a change of state.
Fusion, freezing, evaporation, condensation, sublimation (x2).

Answer 2

Fusion absorbs
Freezing releases
Evaporation absorbs
Condensation releases
Sublimation (gas to solid) releases
Sublimation (solid to gas) absorbs

Question 3

The two changes of state that add water vapour to the atmosphere are:

Answer 3

Evaporation

Sublimation (solid to gas)

Question 4

The two changes of state that remove water vapour from the atmosphere are:

Answer 4

Condensation

Sublimation (gas to solid)

Question 5

Decode: W = Fd

Answer 5

Work = force x distance

Question 6

The water cycle consists of four basic stages, they are:

Answer 6

Evaporation
Transport of water by the air
Condensation and precipitation onto land
Streams flow back to the sea
