A. Boiling and Melting Points
1) What happens to the molecules of a candle when it starts to melt?
2) What happens to the molecules of water when it starts to boil?
B. Density and Specific Gravity
1) A lava lamp is made of special wax and translucent liquid mixture inside a
glass vessel. Explain why the wax can float inside the vessel.

Final answer:

When a candle melts, the molecules transition into a liquid state, while water boiling results in a transition to a gaseous state. The wax in a lava lamp floats due to its lower density compared to the liquid mixture.


Explanation:

Boiling and Melting Points:

  1. When a candle starts to melt, the molecules within the candle gain enough energy to overcome the forces holding them in a solid state, transitioning into a liquid state.
  2. When water reaches its boiling point, the molecules gain sufficient kinetic energy to break free from the intermolecular forces holding them together, transitioning into a gaseous state.

Density and Specific Gravity:

  1. The wax in a lava lamp can float inside the vessel because it is less dense than the translucent liquid mixture, allowing it to remain on top due to its lower density.
