The time needed for water to boil depends on various factors such as the heat source and the amount of water. Generally, it takes around 5-10 minutes for water to boil. Adding salt to water increases its boiling point, meaning it takes longer for saltwater to reach boiling point compared to plain water. However, the difference in boiling time is minimal and may not be noticeable in everyday cooking.
If you boil it, the water will evaporate. If you leave it boiling long enough, you should only have salt left.
No, salt water does not boil faster than water with pepper. Adding salt or pepper to water may change its boiling point slightly, but the difference is not significant enough to affect the time it takes to boil.
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
Both salt water and regular water will boil. However, salt water will have a higher boiling point than regular water due to the presence of salt in the solution.
Water with salt will actually take longer than water without salt to evaporate. This is due to boiling point elevation. If you put a solute into water, it will make it more difficult to boil, and therefore will boil at a higher temperature. Since it takes longer for the salt water to boil, it will take longer for it to evaporate as well
Yes, but only a little.Enough to matter for science done with a stopwatch but not enough to matter for cooking.
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.

Surprisingly, water with a high salt content boils faster than pure water. Salt water may have a higher boiling point than freshwater, but because it takes less energy to increase the temperature of salt water (due to the salt requiring very little energy to heat) the salt water boils faster.
Adding a salt to a substance changes its boiling and freezing points, but it lowers its freezing point and raises its boiling point. So, salt water actually takes more heat to boil because the salt has raised the boiling point.
