Jets do the same thing when air is forced over their wings, though jets cool air by only about 36 degrees Fahrenheit (20 degrees Celsius).
绝对零度(460华师摄氏度)是完全不存在热量的状态;所有物质变得惰性,而且在这样的温度下它们也无法发生化学反应。
Absolute zero (- 460 degrees F) is the total absence of heat; all matter becomes inert and incapable of reaction at that temperature.
