8. Below are the experimentally found dependences of surface tension (mJ / m2) on temperature for melts of a number of metals (melting temperature in ° C is taken as the initial one):
3) bismuth σ \u003d 371 - 0.08 * (t - 271)
Calculate and plot the dependences of surface tension, total surface energy, and heat of formation per unit surface for temperatures exceeding the melting point of the indicated metals by 30, 60, 90, 120, and 150 °C.
