  1. q1 = heat to change T of ice @ -10 C to ice @ zero.
    q1 = mass ice x specific heat ice x (T1-T2) = ? T2 is 0 and T1 is -10

    q2 = heat to change solid water (ice) to liquid water (liquid)
    q2 = mass ice x heat fusion = ?

    q3 = heat needed to change liquid water @ 0 to liquid at +10.
    q3 = mass water x specific heat water x (T2 - T1) = ?

    qtotal = q1 + q2 + q3 = ?
