    I have noted big disagreements of a scale of hundreds of degrees centigrade in published values for the boiling temperature of chemical elements such as tin and gallium.

    For example,

    Tin
    Wikipedia - 2602 C, 2875 K, 
    Chemical Elements website - 2270.0C, 2543.15 K
    which agrees with one of my text books
    Penguin Dictionary of Chemistry - 2270C
    but not the other
    Chemistry, Molecules, Matter and Change - 2720C


    Gallium
    Wikipedia - 2204 C, 2477 K, 
    Chemical Elements website 2403.0 C, 2676.15 K
    which agrees with one of my text books
    Penguin Dictionary of Chemistry - 2403 C
    but not the other
    Chemistry, Molecules, Matter and Change - 2070 C


    Of course I am wondering why the different values - errors by the authors of books or websites or genuine disagreements between scientists as to the values?

    Which source do people recommend as the most reliable source of accurate boiling temperature information and why?
