I think its the same
They are the same. When cold water heats up and bubbles that means it is boiling.
It takes longer to boil, but it's the same boiling point.
it removes bad bacteria by heating the water and reaching it to boiling point
The boiling point of water is not always the same. It depends on water ingredients (e.g presence of salts), pressure on water, and other factors.
Under the same conditions (in particular, at the same surrounding atmospheric pressure), all water at its boiling point will be at the same temperature regardless of its starting temperature.
yes
a puddle of water will evaporate faster because it has a larger surface area that is, it has more of its moleccules in contact with the air Yes, the more air the same amount of water can cover, the faster it will evaporate. In a glass, there is much water that gets tiny amounts of air under the surface and not enough to evaporate. If the same amount of water was poured on a level flat surface (no puddle), it would evaporate very quickly.
It stay the same
The boiling water cools and the freezing water warms up until they are both at the same temperature.
Yes
Obviously not.
