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.

When you change the amount of a substance the time it takes to reach the boiling point then what happens?
The lower the amount of substance, the faster it reaches the boiling point. The more the amount of substance, the longer it takes to reach the boiling point. Hope that this is what you wanted to know! :)
Why pure water is less time to boil than water with salt?
The boiling point of pure water is lower than the boiling point of a water-salt solution, so it takes takes longer to heat the water-salt solution to its boiling point.
Which took more time heating the water from room temperature to boiling point or boiling all the water away?
boiling it
What is the time needed for water to boil and the effect of adding salt?
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.
When you cook pulses at mountain it will take more time or less than at sea level?
on mountains the atmospheric temprature decreases and hence the boiling point of water decreases . so we have to cook pulses on mountains in pressure cookers and not in ordinary vessels. therefore, it will more time

Why does a substance take longer to boil than melt?
because substances boil at a higher temperature than when it melts. therefore, boiling takes more energy than melting and more energy takes more time.
Why does sea water take more time to boil than fresh water?
The increased salt content raising the boiling point of the water, and so it takes longer to reach boiling temperature.
Why pure water is less time to boil than water with salt?
The boiling point of pure water is lower than the boiling point of a water-salt solution, so it takes takes longer to heat the water-salt solution to its boiling point.

How much time do you microwave water to get you t to a boiling point?
it takes about 4 to 5 min..

Does weathering down a mountain take a long time or a short time?
It takes a very long time, hundreds of millions of years.
Why it takes longer time to cook dhal when sodium chloride is added?
It is probable only an illusion; the variation of the boiling point is minimal.
When heating a sample of pure water to the boiling point why doesn't all of the water instantly vaporize when you reach the boiling point?
as each molecule of water evaporates it takes heat with it, lowering the temperature of the surrounding water, so it takes time before every molecule evaporates.
Does the water boil faster with more water?
Slower, the more water, the more time required to reach boiling temp.
