    Hmm, I'm having a hard time explaining why certain elements have high/low boiling points.

    Could anyone explain to me what are the factors, and then put that into a scenario?

    ALSO, what determines thermal conductance? Thanks

    Elements or molecules? Or both? Cause with molecules you get into different types of bonding and the energy it takes to break bonds, etc...

    with elements it's more like what phase are they naturally in, what it takes to get them to melt, what their liquid form is like....etc...

    As in which elements conduct heat better than others/why?


    (Fe)male = male alloyed with iron for greater strength, ductility, and magnetism.

    Intermolecular forces affect the temperature at which compounds boil. Like water for instance. It has a molar mass of 18 g, so it should be a gas at room temperature like other substances with that mass. Instead, it doesn't turn into a gas until 100 degrees C, because of the strong hydrogen bonding.

    I think this page gives some good info about why some things conduct heat.
