Ordinary water boils at 100 degree c.can it be made to boil at 95 degree c. or 105 degree c. ?
Yes---
By increasing the atmospheric pressure, the boiling point of water increases (the principle behind a pressure cooker).
If the atmospheric pressure is decreased, the boiling point of water is decreased.
By adding a solute (dissolving something in the water), the boiling point will also be elevated
