the lava lamp has a light bulb as a heat source at its base. the lamp contains a colored, waxy fluid that can be observed moving in clumps through a clear liquid. as the clump of colored fluid reaches the top of the lava lamp, what has increased to make it start to fall to the bottom again? density temperature kinetic energy of its molecules space between its molecules

the lava lamp has a light bulb as a heat source at its base. the lamp contains a colored, waxy fluid that can be observed moving in clumps through a clear liquid. as the clump of colored fluid reaches the top of the lava lamp, what has increased to make it start to fall to the bottom again? density temperature kinetic energy of its molecules space between its molecules

Answer

Brief Explanations:

When the colored - waxy fluid reaches the top of the lava lamp, it cools down. Cooling causes the fluid to contract, increasing its density. A higher - density fluid sinks in a less - dense surrounding fluid. Temperature decreases as it cools, kinetic energy of molecules decreases with cooling, and the space between molecules decreases as it contracts.

Answer:

density
