### Question 1
The statement that is NOT true about the scenario is:
**The heated water is more dense, which is why it rises.**
When water is heated, it becomes less dense due to the increased space between the molecules, which is why it rises rather than being more dense.
### Question 2
As the water molecules reach the surface of the pot, the correct response is:
**They evaporate into the air.**
While some may gain thermal energy as they reach the surface, the primary process occurring is evaporation, where the water molecules transition from the liquid phase to the gas phase.
