Mar 01, 2020 1. Introduction. Evaporation acts as an exchange function for soil moisture and air water vapor at the land–atmosphere interface (Monteith 1965; Yan and Chen 1990; Ali et al. 2008), and consumes more than half the solar energy absorbed by the land (Kiehl and Trenberth 1997).It is a critical component when measuring the underlying surface water balance and …

The Rotary Evaporator

The Rotary Evaporator It is commonly taught in General Chemistry classes that the vapor pressure of a liquid or solid varies directly with temperature, i.e., the higher the temperature of a substance, the higher its vapor pressure. When a liquid is heated it begins to boil as the liquid turns to vapor forming
