Answer and Explanation:1 A liquid boils when its vapor pressure becomes equal to the external pressure. Therefore if you decrease external pressure, the boiling point will... Learn more about this topic: Vapor Pressure | Definition, Formula...
A liquid boils when its A) temperature is equal to 273 K (standard temperature). B) vapor pressure is equal to, or greater than, the external pressure pushing on it. C) temperature is greater th What would be the effect of either increasing...
1 When the temperature of a liquid is raised enough, the liquid boils. This means that bubbles of vapor, containing millions of molecules, form below the surface. In order for such bubbles to be produced, the pressure of the vapor inside them must be equal to the pressure of the air upo...
When water is a liquid (液体), we drink it or use it to take a shower. When water is a solid (固体), we put some of it into a drink to keep it cool. We like to ski or skate on solid water. When water is a gas, we call it water vapour. When water boils(煮沸),some of...

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 ...
We also know that water boils, or changes feom a liquid to a gas, at 100 Celsius. Research the melting and boiling points of five other substances. How do these melting and boiling points compare to those of water. 固体对液体,在0摄氏。 我们也知道水煮沸或者改变feom液体到气体,在100摄氏。
