What is the meaning of negative pressure evaporation?
Bear the size of the atmospheric pressure, if the pressure is relatively low relative to the amount of evaporation, so easy, or accelerated evaporation can be used to reduce the pressure method is not complete, the negative pressure refers to the ambient pressure down to atmospheric pressure, so the above said
Such as water at an atmospheric pressure is 100 degrees to make boiling and a large number of evaporation, at 0.5 atmospheres of water in more than 80 degrees on the boiling and a large number of hair, which means that the same liquid in other conditions under the conditions of evaporation (volume) and liquid
