(choose chapter or problem)

An ordinary egg can be approximated as a 5.5-cmdiameter sphere. The egg is initially at a uniform temperature of \(8^{\circ} \mathrm{C}\) and is dropped into boiling water at \(97^{\circ} \mathrm{C}\). Taking the properties of egg to be \(\rho=1020 \mathrm{~kg} / \mathrm{m}^{3} \text { and } c_{p}=3.32 \mathrm{~kJ} / \mathrm{kg} \cdot{ }^{\circ} \mathrm{C}\), determine how much heat is transferred to the egg by the time the average temperature of the egg rises to \(70^{\circ} \mathrm{C}\) and the amount of exergy destruction associated with this heat transfer process. Take \(T_{0}=25^{\circ} \mathrm{C}\)
