It entirely depends on how much power or rate of energy flow there is into the water, which requires the latent heat of vaporisation (2.26 x 106 Joules/kg for water) to be supplied. Thus if the energy flow is 1 kW = 1000 Joules/sec, the mass of water evaporated per second will be 1000/2.26 x 106 kg or 0.4425 x 10-3 kg, which means it will take 2260 seconds to evaporate one kg, or about 38 minutes. Obviously in a large power plant where the energy flow might be 1000 MW, this is one million times as much, and you would evaporate 1000 tonnes (a million kg) in the same time.
When boiling water, it evaporates and turns into steam. The amount of water that evaporates depends on factors like temperature and time, but generally, about 10 of the water evaporates when boiling.
No, a large iceberg contains much less heat energy compared to a cup of boiling water. The heat required to raise the temperature of an iceberg even slightly is much larger than that needed to reach boiling point for a cup of water.
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.
When heated, both salt water and regular water evaporate to form steam. However, the presence of salt in salt water can increase the boiling point of water, which can lead to a higher temperature being required to turn it into steam compared to regular water.
A boiling kettle is useful for preparing hot water for drinks or cooking. However, leaving a kettle boiling for an extended period would waste energy unnecessarily. It is best to boil only as much water as needed to be energy-efficient.
Salt does not evaporate with water, so all the salt that was initially in the water remains behind once the water has evaporated. This is because salt has a much higher boiling point than water and remains in solid form when the water evaporates.
Try it!
It depends on how much water that evaporated.
Salt does not evaporate during distillation because its boiling point is much higher than that of water. Distillation separates substances based on the differences in their boiling points, so salt remains behind in the residue as the water evaporates and is collected as distillate.
Eventually, all of it.
The water evaporated first condenses. This condensed water turns into rain.
molecules move quickly and turn into carbon dioxide
No, salt does not evaporate in boiling water. When water boils, it turns into steam, leaving behind the salt in the water. Salt does not have a low enough boiling point to evaporate along with the water.
When boiling water, it evaporates and turns into steam. The amount of water that evaporates depends on factors like temperature and time, but generally, about 10 of the water evaporates when boiling.
Because some of the water is evaporated into the air. Salt water is evaporated much faster than fresh water.
Water being evaporated salts remain as residues.
Much faster in boiling water.
