Question

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 at the bottom of the lava lamp rises to the top, which will increase? its density its temperature the kinetic energy of its molecules the space between its molecules

Answer 1

The correct answer is its temperature. The clump of colored fluid at the bottom of the lava lamp rises to the top because the clump being the heavier liquid will absorb the heat and it will expand, making it less dense and it starts to rise. Once it rises, it cools down, making it denser and heavier.
