An egg with mass 0.0889kg is initially at a uniform temperature of 8°C and is dropped into boiling water at 97°C. The specific heat of the egg is 3.32 kJ/kg.°C. Determine: (a) The amount of heat transfer to the egg by the time the temperature of the egg rises to 70°C. (b) The entropy change of egg in (a). (c) The amount of entropy generation associated with this heat transfer process (to determine entropy generation, we look at extended system that includes the egg and its immediate surroundings). Hint: We worked on similar example 7-21 (liquid-vapor mixture) in class. It will be helpful to study example 7-19 (solid) before starting this problem.
