q1 = heat needed to raise T of ice from -22 to zero C.
q1 = mass ice x specific heat ice x (Tfinal-Tinitial)
q2 = heat needed to change solid 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 22.0 C.
q3 = mass water x specific heat water x (Tfinal-Tinitial)
Total heat = sum q1+q2+q3.
Calculate the amount of heat needed to convert 45g of ice at –22.0°C to water at 22.0°C.
