A block of ice (m = 9 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 = 29 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. Input an expression for the amount of energy, Em, needed to melt the ice into water. Input an expression for the total amount of energy, Etot, to melt the ice and then bring the water to T2. What is this energy in joules?
