How much heat is required to melt 110g of ice at-45°C?

1 answer

q1 = heat need to change temperature of solid ice at -45 C to solid ice at 0 C.
q1 = mass ice x specific heat solid ice x (Tfinal-Tinitial)

q2 = heat needed to change solid ice at 0 C to liquid water at 0 C.
q2 = mass ice x heat fusion water.

Total q = q1 + q2
