Web3 de ago. de 2024 · That means ethanol took away more heat. However, if we look into the tables, we find out that specific heat of vaporization of ethanol (879 kJ·kg -1 ) is about three times less than that of water (2257 kJ·kg -1 ) – it is water that should take more heat away from the straw (if we assume approximately same amounts of water and ethanol stuck … Web6 de may. de 2024 · Why is ethanol used instead of water? Ethanol/water combinations are commonly used because ethanol has good dissolving ability for many organics, but is also infinitely co-soluble with water. Addition of water can rapidly and dramatically reduce the solubility of many organics and thus induce crystallization. joshua\u0027s law approved online courses https://casadepalomas.com
