Gasoline helps cool air?

  1. Feb 25, 2007 #1
    This is just a random question and I know you guys will have the answer:)

    I had read somewhere in the past that the 'molecules' in gasoline help keep the gasoline fluid cooler than the ambient air around it.

    Now (assuming that is true), could you possibly pass air over it (using a fan) and cool the air around it, and that in turn would keep the gasoline temp to constantly drop, because the ambient temp keeps dropping. In theory of course...

    Hope that made sense:) Any thoughts?

    I'm guessing the only cooling is due to evaporation, and I'd recommend you use water instead of hydrocarbons.

    No, this is a violation of conservation of energy. You cant both lose energy to the air and the gasoline at the same time. Heat has to go somewhere. In this case, air --> gasoline. Eventually, the gasoline will reach thermodynamic equilibrium with the air.
