Question

What temperature does water boil?

Answer 1

Boiling point:

• "The temperature at which the vapor pressure of a substance becomes equal to the atmospheric temperature is called the boiling point of the substance."
• At this temperature, the substance starts boiling.

Boiling point of water:

• At one atmospheric pressure, the boiling point of pure water is ${100}^{°}\text{C}$. Water boils at this temperature.
• However, the boiling point changes due to certain factors such as altitude and purity of water.
• At higher altitudes, the boiling point of water decreases while impure water boils at a higher temperature than pure water.
