题目7. When the pressure gets low, the boiling point becomes low.气压低,沸点就低答案B
When water is heated it reach a temperature - the boiling point - at which the vapor pressure is large enough that bubbles are formed inside the water. The boiling point of water depends on pressure. Online Water Boiling Point Calculator The calculator below can be used to calculate the water...
A VERY convenient lecture experiment to show that the boiling-point of liquids is lowered by diminishing the pressure of the surrounding medium, may be made with one of Ducretet's carbon-dioxide tubes. The lower part of the tube contains the COin the liquid condition, while the upper part ...
aPls advice when we can received new Good Quality ICs as the the same has ben delayed for a while now. Pls忠告,当我们能被接受的新的质量好的ICs,因为同样让本有一阵子被延迟现在。[translate] aLow pressure → Low boiling point 低压→低沸点点[translate]...
● Vapor pressure (Vp), boilingpoint (BP) and vapor density (Vd) are three physical properties that aresignificant in determining risk. (蒸气压、沸点、蒸气密度是在决定风险时很重要的3个物理特性。) ● All liquids give off somevapor at their surface. The amount of vapor given off by a liqui...
When the pressure gets low,the boiling-point becomes low。 气压低,沸点就低。相关知识点: 试题来源: 解析 Scientists have been devoted to developing high-yield rice varieties that sparked the green revolution in the 1970s. 科学家一直致力于研究高产水稻品种,引发了20世纪70年代的绿色革命。
