Place it in a freezer and allow it to freeze. Use of liquid nitrogen is a very quick method of doing so.
Decrease the temperature and make it turn into ice.
0o Celsius or 32o Fahrenheit.
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).
Melting
you pee on it
You don't decrease the temperature, you raise the water's boiling point, or increase the water's temperature......
by boiling
Yes, that is partially true. While water is being heated, once its temperature reaches boiling, the water will remain at boiling until all of the water boils away. So, Yes, it does turn to gas, but, No, it doesn't turn to gas all at once. Prior to reaching boiling, the water would have been evaporating at a slower rate. The only thing magical about the boiling point is that is the temperature where the pressure of the evaporating water equals atmospheric pressure.
Salt lowers the boiling temperature of the water allowing to turn down the heat source
Boiling is to heat an liquid to the point where it will turn from a liquid to a gas. Because the substance cannot be at temperature higher than its boiling point the temperature will remain that until all the liquid has been boiled away. That is why if I were to heat some alcohol and water the temperature would remain at about 60oC until all the alcohol had evaporated away. Then the temperature would go to 100oC and the water would boil. The boiling point of substance is the temperature at which the substance will turn from a liquid to a gas. This is about 100oC for water.
Yes, turn the heat off. Boiling water does not change its molecular structure, so, yes, it can be "unboiled."
Pour hot water (not boiling) over the key hole and door seams, gain access immediately and turn on defroster and turn heat
