A 250 g mass of material has a temperature of –45˚C. Its specific heat is 0.36 J/gˑ˚C. How much heat energy is required to raise its temperature to 10˚C? (its melting point is 23 ˚C)

Answer 1

Since the melting point is above the final T you need not worry about a phase change.
q = mass x specific heat x (Tfinal-Tinitial).
