When an aluminum bar is connected between a hot reservoir at 860 K and a cold reservoir at 348 K, 2.40 kJ of energy is transferred by heat from the hot reservoir to the cold reservoir
(a) In this irreversible process, calculate the change in entropy of the hot reservoir.
J/K
(b) In this irreversible process, calculate the change in entropy of the cold reservoir.
J/K
(c) In this irreversible process, calculate the change in entropy of the Universe, neglecting any change in entropy of the aluminum rod.
J/K
(d) Mathematically, why did the result for the Universe in part (c) have to be positive?
