Text and Images from Slide

Image of a pot of soup heating up to show convection

Heat conducts into the pot and from the pot into the soup

Heat radiates into the air.

Fig 10.2

So just like the lava lamp, density differences (from heating) and gravity cause a cycling of material and transfer of heat.
