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 run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is...
four parts of water and five parts ofANTI-antifreeze reduce this to -22℃.FREEZE②Alcohol is a kind of good antifreeze,but when the car is running, it becomes hotand the alcohol boils away, so it must be changed very often.Most people use antifreeze that does not boil away when the...
Most peopleuse antifreeze that does not boil away when the engine is running. T here are several chemicals that do this. One of the most popular is called ethylene glyco.People use to keep car engines cool.A.antifreezeB.waterC.alcoholD.ethylene glycolWe use antifreeze in order to .A.keep...
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 e

How does evaporation cause cooling? What happens when lightning strikes the ground? How does sugar act as antifreeze for ice cream? What happens when lightning strikes near you? How is cooling caused by evaporation? What happens when the pressure of a gas is lowered?
Ice recrystallization is a phenomenon observed as the increase in ice crystal size within an already frozen material. Antifreeze proteins (AFPs), a class of proteins capable of arresting ice crystal growth, are known to inhibit this phenomenon even at su

Approaches to the freezing pipe problem in a building where heat is left on but pipes still freeze include: Reliable heat: Make sure the heating system itself doesn't freeze-up. For hot water heat, add antifreeze to the system. Drafts: Find and fix piping exposed to cold drafts Uninsulated...
Special proteins inside the frog’s body freeze the water in the frog’s blood. Water forced out of the frog’s other cells freezes as well. But a special solution produced inside the frog acts like antifreeze in a car, protecting the cells. In cold temperatures the frog’s heartbeat, ...
