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.

Predict whether water would boil on top of a mountain at a higher or lower temperature than at sea level?

Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.


Does amount of water effect how long it takes to boil?

Yes. The more quantity of water there is the more time it takes to boil than a less quantity of water. No I don't think so because it depends on the temperature on which it is the boiled.If it is more,then the water boils fast. Of course if it is more water,then it needs more temperature than less quantity of water.
