A lava lamp contains colored liquids. These liquids form globs that rise and fall in the lamp. This is due to ____.

• convection

• conduction

• radiation

Answer explanation

Convection is the main mode of heat transfer as heat from the light at the bottom, causes the wax to rise and fall in a cyclical motion due to changes and density.

Conduction plays a minor role in transferring heat from the bulb to the wax.
