To solve this problem it is necessary to apply the concepts related to heat exchange and Entropy.
The temperature and mass remain constant, therefore the entropy values will be the only ones to change.
Of the three elements given their entropy values are given by
Part A) From thermodynamic theory we know that temperature is inversely proportional to entropy
Energy remains constant
Therefore the order would be
Lowest Temperature= Water
Medium Temperature= Glass
Highest Temperature=Iron
Part B) In the case of Energy the opposite happens because it is proportional to the entropy, then
Temperature is constant
Lowest Energy = Iron
Medium Energy = Glass
Highest Energy = Water
