Question

What are the methods used to increase the boiling point of water in pressure cooker and in the radiator of vehicles

Answer 1

In presuure cooker boiling pointof water is increased by increasing its pressure. You can increase the pressure above the boiling water. The boiling point of a liquid varies depending upon the surrounding environmental pressure. A liquid in a partial vacuum has a lower boiling point than when that liquid is at atmospheric pressure. A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. In radiator of vehicles, boiling point of water is increased by adding an additive called antifreeze. The specific heat ofantifreeze(pure or mixed withwater) is lower than that of purewater. Anantifreezeis an additive whichlowersthe freezingpointof a water-based liquid andincreasesitsboiling point.
