Why boiling point of water is less than 100°c in the laboratories |
|
Answer» Water boils at 100°C or 212 F at one atmosphere of pressure. Liquids boil when the pressure of the atmosphere is equal to the pressure of the liquid. When the pressure of the atmosphere is reduced a liquid boils at a lower temperature. This is what happens when you climb a mountain. When pressure cooker is used steam is trapped in the pot and it increases the pressure above the water. this causes the water to boil at a temperature more than 100°C. when you pull back on the plunger, the pressure in the syringe is reduced and the liquid boils t a lower temperature. You can boil water at about 50°C in this system. |
