q1 = heat needed to raise T of ic from -14C to 0C.
q1 = mass ice x specific heat ice x (Tfinal-Tinitial)
q2 = heat needed to melt ice at zero C to liquid H2O at zero C.
q2 = mass ice x heat fusion
q3 = heat needed to raise T of liquid water from zero C to 24.0C
q3 = mass liquid H2O x specific heat H2O x (Tfinal-Tinitial)
qtotal = q1 + q2 + q3.
q1 = mass ice x specific heat ice x (Tfinal-Tinitial)
q2 = heat needed to melt ice at zero C to liquid H2O at zero C.
q2 = mass ice x heat fusion
q3 = heat needed to raise T of liquid water from zero C to 24.0C
q3 = mass liquid H2O x specific heat H2O x (Tfinal-Tinitial)
qtotal = q1 + q2 + q3.
