Why does 2 liters of boiling water not have twice as great a temperature as 1 liter of boiling water?
Boiling point is an intensive property, which means that it is not dependent on the amount of a substance, such as water.
The boiling point of water is an intensive property , which means it is not dependent on the amount of water. However, it is dependent on altitude. So water at the same altitude will have a specific boiling point, regardless of the amount of water. It will, however, affect the amount of time required to reach the boiling point.
