D Antifreeze is a liquid(液体) that is added to water to keep it from freezing. When water freezes and turns to ice, it expands(膨胀). The force of water expanding is so great that it will break the hardest metal. Water is used in car engines(发动机) to keep them cool while they ...
An antifreeze (防冻剂) is a liquid that is added to water to keep it from freezing. When water freezes and turns to ice it expands. The force of water expanding is so great that it will break the hardest metal. Water is used in car engines to keep them cool while they run and if...
① Water is used in car engines tokeep them cool while they run, and if this water is allowed tofreeze in winter, it can break the iron block of the engine.That is why antifreeze is necessary.Water freezes at 0C; the usual kind ofantifreeze will not freeze until thetemperature is -...

Antifreeze solutions are costly and may be difficult to maintain. Antifreeze is usually used for small, unheated areas. 防冻液: 防冻液在管道系统增加到水被暴露在凝固温度。 当洒水喷头熔化时系统运作,以与湿用管道输送系统相似的方式。 防冻液是昂贵的,并且也许是难维护。 不冻液为小,未加热的区域通常...

Engines often let drivers know they’re about to overheat. Here are four of the signs: A strange, sweet smell coming from the engine area (this could be the scent of leaking radiator fluid, otherwise known as coolant or antifreeze) Steam that may look like smoke coming from under the hood...
How many liters of water must be added to 20 liters of a 70% antifreeze solution to produce a 50% solution? Why is there more water vapor in expired air than inspired air? Why does a thermocouple have to be amplified? How does the addition of sulphuric acid produce hexaaquacopper(II)...
