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. ...
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...
