Steam, a first-class Chinese word, refers to the gas transformed from steam, liquid or solid; Especially water vapor. Say "Wen Jie Zi Zhu" and (steam) the water dry. Daya people are old in Sichuan and Guangdong. Mao, danger also. There is no well in the branches of Zhouyi. The fox helps the poor. Yu Fan said. Mao, Ji Ye. They are all extended meanings. When the water is dry, it will run dry. So the extended meaning is "danger" and "several". From the water.
Extended data:
1, Overview of Water Vapor
Water vapor is the gaseous form of water (H2O). When water reaches the boiling point, it becomes steam. At the standard atmospheric pressure at sea level, the boiling point of water is 99.974°C or 212 F or 373.15 K. ..
When water is below the boiling point, it can also slowly evaporate into steam. However, in the extremely low pressure environment (below 0.006 atmospheric pressure), ice will sublimate directly into water vapor. Water vapor may cause the greenhouse effect. It is a greenhouse gas.
2. Changes of rain and white gas caused by steam.
At room temperature, water will slowly turn into steam and fly into the air. This phenomenon is called evaporation. The water on the ground turned into steam, forming clouds in the sky; If water vapor condenses into larger water droplets, the water droplets will fall to form rain or snow.
When a large amount of water vapor condenses in the air, it often presents a mass of "white gas", which is often mistaken for water vapor. By comparing the color, shape and position of "white gas" and water vapor, we can know that "white gas" is not water vapor, but small water droplets condensed by water vapor floating in the air. Generally we call it "white gas" fog.
3. Evaporation phenomenon
The process of water changing from liquid or solid to gas and escaping into the atmosphere is called evaporation. Refers to water contacting with air at normal temperature and turning into steam. Evaporation refers to the amount of water dispersed into the air through evaporation in a certain period of time.
Usually expressed in millimeters of the thickness of the evaporated water layer, the evaporation of water on the water surface or soil is measured by different evaporators. Generally, the higher the temperature, the smaller the humidity, the greater the wind speed, the lower the air pressure and the greater the evaporation. On the contrary, the smaller the evaporation.
