At 760 mmm col. Hg pure water boil at 100 0C.
A quick way to make a liquid boil without heating it is to place a container of the liquid in a vacuum chamber and start pumping out the air. Seawater is distilled with a big help from the reduction of pressure on it. That way it doesn't have to be heated so much to cause it to change to steam. Modern naval ships have water desalination facilities on board that rely in part of the idea of reduction of pressure to lower the boiling point of the water. It's faster and more energy efficient.
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
Boiling point of water is an intensive property because it does not depend on the amount of the substance present. Water will always boil at 100 degrees Celsius at standard atmospheric pressure regardless of how much water is being heated.
Water boils when its vapor pressure equals the vapor pressure of the surrounding atmosphere. The atmosphere surrounding the water exerts a pressure, preventing gas molecules escaping from the surface. At higher altitudes, this pressure is much lower so water will boil at a lower temperature.
Air pressure and moisture in the air can affect the length of time it takes for something to start boiling. But the affect would not be very high I must say, this is an interesting question. I do not believe that weather affects how long water takes to boil unless you are outside. I am not a physics professor, however.
Boiling of a liquid: The temprature at which the vapour pressure of a liquid becomes equal to the external pressure is called boiling point. So the atmospheric or external pressure on mount everest is low. Thats why water boils quickly.

It has to be 212 or better to boil so at least that much.
YesThis is because boiling is caused by the liquid water turning to gas which is not influenced directly by other materials. However, once in a vacuum the pressure is so low that the water will boil at much lower temperatures.

Water would boil immediately on Mars because the atmospheric pressure is much lower than on Earth. This causes the boiling point of water to be much lower, so it would vaporize rapidly when exposed to the low pressure conditions on Mars.
When the pressure is reduced. Water only boils at 100 degrees Celsius when the air pressure is one atmosphere. So up a mountain, where the air pressure is lowered, water boils at a lower temperature.
That is entirely dependent on: 1. Your relation to sea level. 2. How much water you have. 3. How much salt is in the salt water. 4. What amount of heat you are using.
Due to the high altitude the atmospheric pressure is much lower than at sea level. This allows the water to boil at a much lower temperature. Since boiling occurs when the vapor pressure reaches the atmospheric pressure. Since you can't get water hotter than the boiling point your cup at such a high altitude will never get very hot.
Use Flour and Boil Water For Three To Four Minutes Then Let It Cool
You can make tea. It doesn't have much, if any THC in it, but I think it tastes pretty good. Just boil water with the stems in it for a while. The long you boil, the stronger the flavor will be.
Water boils when the vapor pressure due to the temperature of the water is equal to the pressure outside. The air pressure on mountains is slightly less because there is less atmosphere above you, so water boils at a lower temperature (only by a few degrees, though) at higher altitudes. Because of this, you need to boil food at higher altitudes longer to compensate and make sure it is cooked as much as if you boiled the same food at a higher temperature at a lower altitude for a shorter amount of time.
