For question 1, the statement that is NOT true about the scenario is:
The heated water is more dense, which is why it rises.
This statement is incorrect because heated water is actually less dense than cooler water, which is why the warmer water rises.
For question 2, as the water molecules reach the surface of the pot, the correct response is:
They evaporate into the air.
This describes the process occurring as water molecules gain energy and transition from the liquid phase to the gas phase.
