Volatility and heat loss

  1. Jun 15, 2013 #1
    When we have ethanol on our skin it feels colder than when we have water on our skin. The explanation given was that more energy is required to turn one molecule of liquid ethanol to gaseous ethanol than for one molecule of liquid water. However, in that case won't more of the water evaporate too? So why would ethanol feel colder?

    Ethanol evaporates faster.
