WebThe evaporation from the surface can be calculated as. g s = (34.5 kg/m 2 h) (1000 m 2) ((0.014659 kg/kg) - (0.0098kg/kg)) / 3600 = 0.047 kg/s. The evaporation heat (enthalpy) … WebEvaporation is an endothermic process that results in a temperature decrease. Evaporating molecules carry away thermal energy when they leave a liquid. The amount of temperature decrease is related to the strength of intermolecular forces of attraction. Alkanes and alcohols are two types of organic compounds. Alkanes have carbon and hydrogen atoms.
