Three reservoirs of heated water are represented on the entropy diagram in Figure P21.8. All three reservoirs contain equal amounts of energy, so that \(E_{1}=E_{2}=E_{3}\).

(a) For which reservoir would you be least concerned about burning yourself if you dunked your hand into the water?

(b) Which reservoir is most useful for converting thermal energy to mechanical energy?
