Answer 1

2nd, 3rd, and 5th are the answers

Answer 2

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

Step-by-step explanation:

Generally, a lava lamp is made up of wax mixture and a clear surrounding liquid. In principle, the wax in the lava lamp is warmer than the surrounding liquid. In addition, the density of the wax mixture is usually less than the surrounding liquid. When the wax mixture is warmed, it flows through the clear surrounding liquid and exchange heat energy with the liquid.
