this is a lava lamp. when the light bulb heats the wax, the wax rises. when the wax cools, it falls. this cycle of rising/falling is an example of: (1 point) conduction convection radiation none of the above
Answer
Brief Explanations:
Conduction is heat transfer through direct contact. Convection is the transfer of heat by the movement of a fluid (in this case, the wax acts like a fluid). Radiation is heat transfer through electromagnetic waves. In a lava - lamp, the heating and rising of wax and its subsequent cooling and falling is due to the movement of the wax as a fluid, which is convection.
Answer:
B. convection
