That would be when the world began and water was present.

The boiling water will evaporate (turn to vapor). The ice will melt (turn to liquid) and then begin to evaporate (turn to vapor). The tap water will begin to evaporate (turn to vapor).
Yes
False.
That is the boiling point of oxygen. So if the temperature in going downwards then oxygen will begin to liquefy whereas if the temperature is rising, then liquid oxygen will begin to boil.
When bacteria are boiled the heat energy from the boiling water transfers through to the cells of the bacteria causing the water inside them to begin boiling as well. This increases the pressure inside the cells until they bursts, killing the bacteria. However boiling water will not have this effect on all bacteria.
Boiling is the phase where the boiling occurs. The point at which the boiling occurs is the boiling point.
Thicker leather will be stiffer to begin with. To make a floppy leather hat stiffer, immerse it in boiling water, then shape it before it hardens. There are on-line instructions for this. Too much boiling, and the leather will become brittle.
If you add pasta to cold water, and then bring it to a boil, the starches will begin to dissolve. This will cause a very sticky surface on the pasta, and it will clump together. By adding the pasta to boiling water, the surface starches cook right away.
Some volcano words are: boiling hot lava molten metamorphic rock erupting tall volcano(of course)
Never add a boiling chip to a hot liquid, because it can cause immediate boiling over of the solution. If you forget to add a boiling chip before you begin, you must cool the solution before adding one to prevent product loss. "Porous" boiling chips cannot be re-used since the pores inside these stones become filled with liquid on cooling. "Sharp" boiling chips like silicon carbide or coal can often be reused until they become coated with guck and become ineffective.
