Homework Help: Is there any corrolation between thermal conductivity coefficient and molecular wi

  1. Jan 1, 2010 #1
    is there any corrolation between thermal conductivity coefficient and molecular wieght Mw

    according to the units [K] W/(m·K) it is independant of mass units (kg or g/mol etc)

    in my question i am asked to show with a graph, but i have no idea what graph they are talking about

    Put thermal conductivity coefficient of Y axis and Mw on X axis and plot data points for any number of substances (the more, the better). Either there will be some obvious correlation or not.

    You may also try to make a plot for some selected group of substances, like alkali metals, or metals in general.

    using

    Al; Cu; Ag; Au; Pb

    this is the graph i got

    but how do i know if there is any correlation, i know its not linear,
