This depends on many factors.
The time it takes for 1 gallon of water to evaporate on a stove depends on various factors such as the heat setting, the size and type of pot used, and the humidity level in the air. However, under typical conditions, it can take roughly 15-30 minutes for 1 gallon of water to fully evaporate on a stove.
It could take between one and four months for a cup of water to evaporate indoors at 65 degrees depending on the surface area and the humidity.
I don't frickin know
The time it takes for fresh water to evaporate depends on various factors such as temperature, humidity, surface area, and air movement. Generally, it can take a few days to a couple of weeks for a small container of fresh water to completely evaporate at room temperature.
There is no standard length of time that it takes for a gallon of water to freeze. The amount of time it takes for a gallon of water to freeze can vary depending upon many different things such as temperature.
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.
No, water can evaporate at temperatures lower than 0 degrees Celsius, as long as there is enough heat energy present. The process of evaporation occurs when water molecules gain enough energy to escape from the liquid phase and enter the vapor phase.
This is not true.
All tempertures, it just evaporates faster as temperature rises until it boils @ 212 and it evaporates the fastest. It even evaportes when frozen. Under atmospheric pressure, water evaporates at 100 o C (or 132 o F). However, the higher the water pressure, the higher its boiling temperature (or the temperature at which water evaporates).
This will depend on how much vinegar you are looking to have evaporate. Vinegar is a mixture of acetic acid and water. Acetic acid will evaporate faster than water at a rate of .97.
I will be astonished if you show me a river at 100 degrees Celsius in which the water is not actually boiling, let alone evaporating. Perhaps you mean: why does water in rivers evaporate at temperatures below 100 degrees Celsius. To which the answer is: water has a finite vapor pressure at every temperature; if that vapor pressure exceeds the partial pressure of water vapor in the atmosphere above the water, some of the water will evaporate until the partial pressure is equal to the vapor pressure. Even ice evaporates. Make some ice and leave it in your freezer for a long time. The ice cubes will shrink.
