A 10.0 g sample of ice at −15 °C is heated at 1 atm until it has completely melted at 0 °C. If 3.34 kJ of energy is required for the melting step, what additional quantity of heat is needed to raise the temperature of the ice from −15 °C to 0 °C?
(Specific heat capacity of ice = 2.09 J g⁻¹ °C⁻¹.)
a) 3.34kJ
b) 0.314kJ
c) 0.627kJ
d) 3.65kJ
