VI REFLECTION

As a student, why is it important to cite evidence in supporting a general statement?

________________________________________________________________

Answer:

When heated, the wax mixture becomes less dense than the water, because it expands more than water when both are heated. It also becomes fluid, causing blobs of it to ascend to the top of the lamp.

Explanation:

The vessel is placed on a box containing an incandescent light bulb whose heat causes temporary reductions in the density of the wax and surface tension of the liquid. As the warmed wax rises through the surrounding liquid, it cools, loses its buoyancy, and falls back to the bottom of the vessel in a cycle that is visually suggestive of pāhoehoe lava, hence the name. The lamps are designed in a variety of styles and colors.
