Question

How many kilojoules of energy are needed to convert 104 g of ice at -14.6 to water at 25.8°C? (The specific heat of ice at -14.6 is 2.01 J/g°C.)

Answer 1

q1 = head needed to raise T of solid ice at -14.6 (is that C?) to zero.
q1 = mass ice x specific heat ice x (Tfinal-Tinitial)

q2 = heat needed to melt ice.
q2 = mass ice x heat fusion

q3 = heat needed to raise T of water from zero C to 25.8 C.
q3 = mass H2O x specific heat H2O x (Tfinal-Tinitial)

Total Q = q1 + q2 + q3

Answer 2
