3), at 298 K and 1 bar (henceforth, we refer to these as 1 &215; 1 and 3 &215; 3 nm 2 surfaces, pdf respectively). The kinetics of vapor-liquid exchange in water are poorly understood, yet may be critically important in predicting changes in Earth’s climate and understanding the water isotope record preserved rates in ice cores. So, additional agitation is required. Subsequently, the temperature of the cryogenic pool drops down, as the heat taken by evaporation exceeds the heat. Heat from the sun, or solar energy, powers the evaporation process.
