How does diffusion vary from gas to liquid to solid? Explain how convection currents are produced in the air. How does salinity affect density? How does heat move from one place to another in the troposphere? How does the polar property of water relate to cohesion?
Explain how heat energy is transferred by conduction, convection and radiation. What drives surface currents? Why does the high specific heat of water have to do with convection currents in the air at the seashore? Describe the typical path(s) for hurricanes. Is this part of the pattern of ...

How is it possible for a fabric (textile) to conduct the 3 modes of heat transfer (conduction, convection, and radiation)? Why does sound travel slower in cold air than in warm air? Explain why an air conditioner must cycle on and off to keep the room cooled to a preset temp?
The air gap reduces heat losses from the walls by both conduction and convection: conduction, because heat can't conduct through gases; convection, because there's relatively little air between the walls and it's sealed in, so convection currents can't really circulate....
convective zone - where convection currents carry energy toward the surface However, the interior may vary with respect to the location of the layers. Stars like the Sun and those less massive than the sun have the layers in the order described above. Stars that are several times more massive...
