When cooking milk, in order to maintain the nutrients of milk, can not be boiled at high temperatures, for this reason, people have created a "low-pressure pot". With this kind of pot to cook milk.
| The lower the gas pressure on the surface of the liquid, the lower the boiling point of the liquid |
| In order to maintain the nutrients of the milk can not be used to boil at high temperatures, with a "low-pressure pot" to cook milk is the use of lowering the gas pressure on the surface of the liquid to lower the boiling point. The use of the lowering of the gas pressure on the surface of the liquid to reduce the boiling point. The answer is: the lower the gas pressure at the surface of the liquid, the lower the boiling point of the liquid |
