But when the temperature of the air was higher, the evaporation rate was lower.
WebI agree with Sergey, there will be no problems with methanol and/or chloroform. 2 ml water need about 5-10 min at 30°C with our rotary vapors (5 mbar). WebThe boiling point is defined as the temperature at which the saturated vapor pressure of a liquid is equal to the surrounding atmospheric pressure. The boiling point at atmospheric pressure (14.7 psia, 1 bar absolute) for some common fluids and gases can be found from the table below: Product. Boiling Point at Atmospheric Pressure.
