How does a lava lamp work using conduction?

A lava lamp operates through convection rather than conduction, but conduction plays a role in the heating process. When the lamp is turned on, the light bulb at the base heats the wax inside the lamp through conduction, transferring heat from the bulb to the wax. As the wax warms up, it becomes less dense and rises, creating a flow that resembles lava. When it cools at the top, it becomes denser and sinks back down, repeating the cycle and producing the characteristic bubbling effect.
