a当水蒸气通入液相,由于汽相中硫化氢和氨组分的分压低于平衡时蒸气压,所以它仍由液相转入气相。 When the steam passes over the liquid phase, because in the vapor phase the hydrogen sulfide and the ammonia component differential pressure is lower than time the balance vapor tension, therefore it ...
Explain why water vapor turns into a liquid as it cools. Why does temperature increase when water condenses? Why is water liquid at room temperature? Why is a gas easier to compress than a liquid or a solid? Why does evaporation lower the temperature of a liquid?
acondensation: the change of gas or vapor to a liquid;either by cooling or being subjected to increased pressure.When water vapor cools in the atmosphere,for example,it condenses into tiny drops of water,which forms clouds. 结露: 气体或蒸气的变动对液体; 通过冷却或被服从到增加的压力。例如时...
When it is below 0C,water is solid, such as ice or snow. When the water is warm, it is liquid. When the temperature readies 100℃ or higher, it becomes vapor.()31. How can we use water when it is a liquid? A. We drink it. B. We ski on it. C. We put it into a ...
Water freezes at 0 degrees Celsius. When water freezes, it turns into ___. A. ice B. steam C. water vapor D. liquid 相关知识点: 试题来源: 解析 A。本题考查物理常识。水在 0 摄氏度时结冰,变成冰,选项 A 正确。选项 B 蒸汽是水加热到一定温度变成的;选项 C 水蒸气也是水加热后的状态;选...
Suppose liquid water and water vapor exist in equilibrium in a closed container. If you add a small amount of liquid water to the container, how does this affect the amount of water vapor in the container? Is water vapor a gas or solid? Explain. ...
Water vapor condensing to liquid water is what type of process? Define a solid, a liquid, and a gas. What is the change in heat when 23.5 g water vapor at 100 C condenses to liquid 18.50 C? 1. Which of the following processes release the heat? a. vaporization b. sublimation ...
Water vapor is found in the air we breathe. When it’s warm and there is a lot of water vapor in the air, it can feel very sticky (闷热的) and swcaty. When the air cools, the water vapor in it turns into liquid water.
