Question

A block of ice (m = 11 kg) at a temperature of T1 = 0 degrees C is placed out in the sun until it melts, and the temperature of the resulting water rises to T2 = 23 degrees C. Recall that the specific heat of water is c = 4186 J/(kg⋅K), and its latent heat of fusion is Lf = 3.34 × 105 J/kg.

A:  Input an expression for the amount of energy, Em, needed to melt the ice into water.

B: Input an expression for the total amount of energy, Etot, to melt the ice and then bring the water to T2.

C: What is this energy in joules?
