Transfer of Heat: Convection and Radiation

What is the primary method by which heat moves through a fluid?

Which method of heat transfer can occur through empty space, where no atoms are present to conduct or convect heat?

When part of a fluid is heated, it expands and becomes less dense than the surrounding fluid, so it ______, carrying heat with it.

The diagram below shows a fluid being heated from below, setting up a circulating current.

What effect do convection currents like these have on the process of diffusion within the fluid?

Metal pipes are sometimes run through a fireplace to increase its heat output into a room. Heat first moves into the pipe walls, then through the metal walls by conduction, and finally out into the room air by which method?

Why are white clothes recommended for hot, sunny locations?

A vacuum flask has two glass walls with a vacuum between them, and the facing surfaces are silvered.

Select the two methods of heat transfer that the vacuum between the walls blocks (as opposed to the silvering, which reduces the third).
