refer to the image of a lava lamp to answer the question. in a lava lamp, a waxy substance rises and falls repeatedly. what causes the waxy substance to rise? check all that apply. the waxy substance is cold. the waxy substance is warm. the waxy substance is less dense than the surrounding liquid. the waxy substance is more dense than the surrounding liquid. convection is occurring.

Answer

Brief Explanations:

When the waxy substance in a lava - lamp is warmed, it expands and becomes less dense than the surrounding liquid. This causes it to rise. Convection is also occurring as there is a transfer of heat and movement of the substance due to density differences. Cold substances are denser and would sink, and a more - dense waxy substance would not rise.

Answer:

The waxy substance is warm. The waxy substance is less dense than the surrounding liquid. Convection is occurring.
