Select
ALL
the forms of energy needed to make a lava lamp work.
Mechanical energy
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.
Once the density of the material is greater than the water, it begins to sink.
The materials inside the lava lamp are heated at different rates, changing their densities.
Once the material is back at the bottom of the lava lamp, the process repeats.
Question 5
5.
What are other real-life examples that convert electrical energy to light or thermal energies?
A toaster
A lightbulb
Question 1
1.
Which form of energy allows the lightbulb to turn on?
Light energy
Mechanical energy
Thermal energy
Question 2
2.
Which forms of energy does the lightbulb convert electrical energy to?
Sound energy
Electrical energy
Electrical energy
Light energy
Thermal energy
Sound energy
After the heated material floats to the top away from the heated lightbulb, it begins to cool, causing the density to increase.
Light energy is produced by the lightbulb.
Electrical energy is used to turn on the lightbulb.
A hot air balloon
An oven
A speaker
