If you continue to boil water for 2 hours, or any extended length of time, it will evaporate, i.e. turn to steam (water vapor). Depending on how much water you have to begin with, and how long it let it boil, it could all evaporate, or only some will evaporate.
Water will boil at a lower temperature 2 miles below sea level due to the increase in pressure. Generally, water boils at approximately 250°F at that depth, but it can vary slightly depending on other factors.
There are 2 hours in 7200 seconds.
57.73 watt-hours load for 24 hours It takes about 1 Kw of electricity to produce 3.5 lbs of steam from and at 212 F That is 970.2 btu of heat for every 286 watts. 1/2 gallon of water is 4.17 lbs of water. to raise the temperature and convert 1 lb to steam at 100% quality requires 1127.2 btu. for 4.17 lbs that is ~4700 btu. dividing that by 970.2btu/286w = ~1386 watts of energy needed. dividing that by 24 hours will give you a continuous load of 57.73 watt-hours for 24 hours to evaporate 1/2 gallon of water, exclusive of heat losses.
7200 seconds is equal to 2 hours because there are 3600 seconds in an hour (60 seconds x 60 minutes). So, 7200 seconds / 3600 seconds per hour = 2 hours.
To make cloud ice at home, you can try using a method called supercooling. Start by boiling distilled water and letting it cool to room temperature. Then, place the water in the freezer for about 2 hours, making sure not to disturb it. After 2 hours, carefully remove the water from the freezer and pour it into a container. You can then initiate the freezing process by adding a small piece of ice or tapping the container. This should cause the water to instantly freeze and form cloud ice. Remember to handle the process with caution to avoid any accidents.
1. Boiling in hot water. 2. Boiling on vapour.
when it (water) boils or freezes
Water boils at 100 degrees (at standard pressure), so it is probably a little less than that.
At 0,5 bar water boils at about 176 °F or 80 °C At 1 bar water boils at about 212 °F or 100 °C At 2 bar water boils at about 250 °F or 120 °C See the link below for a graph, a table and an explanation.

Throw it away. An egg can only stay under water for 2 hours.
Water will boil at a lower temperature 2 miles below sea level due to the increase in pressure. Generally, water boils at approximately 250°F at that depth, but it can vary slightly depending on other factors.
2 hours to 7 hours, depends on the engine size.
When CaO is put into water it does not dissolve. It reacts with the water to form Ca(OH)2 and releases heat (this is an exothermic reaction) The heat of reaction boils the water.
One to two, depending on the day.
