However, the rate of evaporation will depend on the surrounding air temperature and humidity. Suffice to say, ethanol evaporates quite rapidly with respect to water due to its relatively low specific heat capacity and high vapor pressure. Compared with water, alcohol has a lower heat of evaporation. In his professional life, hes a real-estate businessman. Rubbing alcohol is a type of denatured alcohol, which is a mixture of ethanol and other chemicals that make it poisonous.
