Question 4
4.
Place the steps below in sequential order of how a lava lamp uses and converts energy.
As one material heats up, it becomes less dense and floats toward the top.
Thermal energy is produced from the lightbulb being on for a while.
After the heated material floats to the top away from the heated lightbulb, it begins to cool, causing the density to increase.
The materials inside the lava lamp are heated at different rates, changing their densities.
Light energy is produced by the lightbulb.
Once the density of the material is greater than the water, it begins to sink.
Once the material is back at the bottom of the lava lamp, the process repeats.
Electrical energy is used to turn on the lightbulb.
