Answer:1. When the heating element is turned on, it warms the bottom of the glass container, heating the liquid wax or oil.
2. As the liquid near the bottom is heated, it becomes less dense and begins to rise towards the top of the lamp. This is because warm fluids tend to expand and become lighter than cooler fluids.
3. As the warm liquid rises, it moves away from the heat source towards the top of the lamp. This movement is known as convection currents.
4. As the warm liquid reaches the top of the lamp, it cools down due to the cooler ambient temperature. This causes the liquid to become denser and heavier.
5. The cooler and denser liquid then sinks back down towards the bottom of the lamp. This completes the convection cycle.
6. Throughout this process, blobs or globules of wax or oil rise and fall, creating the mesmerizing and characteristic lava lamp effect.
Explanation:
Convection is responsible for the continuous circulation and movement of the liquid inside the lava lamp. It is the underlying mechanism that produces the distinctive flow and patterns observed in a lava lamp.
