You decde to have 2 hard boiled eggs for breakfast and prepare them by placing 2 refrigerated eggs into a pot of boiling water. Calculate the heat transfer to the eggs in kj and the entropy gemeration in kj/K of this cooking process if you allow the eggs to boil long enough to reach uniform temperature of 70 C. Rho of the egg is 1020 kg/m^3 and Cavg,egg = 3.32 kj/kg*K.
