Calculate the heat energy release when 29.7 g of liquid mercury @ 25.00 degrees C is converted to solid merury at its melting point.
q1 = heat released in moving from 25 C to -38.83 C.
q1 = mass Hg x specific heat liquid Hg x (Tfinal-Tinitial)
q2 = heat released by phase change Hg at -38.83 from liquid to solid.
q2 = mass Hg x heat fusion.
Total = q1 + q2.
q =mass Hg x heat fusion = ?
