Dec 07, 2022| the higher the vapor pressure, the more easily the metal evaporates.
According to the theory of phase equilibrium, the equilibrium pressure (vapor pressure) of the vapor acting on the metal surface is different at different temperatures. High-temperature vapor pressure is high, solid metal evaporation is large; If the temperature is low, the vapor pressure is low, and if the temperature is constant, then the vapor pressure is going to have some value. When the outside pressure is less than the vapor pressure at that temperature, the metal will evaporate (sublimation >). As camphor evaporates in the air from a solid to a gas by sublimation. The lower the external pressure, the higher the vacuum, and the easier it is to evaporate. Similarly, the higher the vapor pressure, the more easily the metal evaporates.
