Question:

A block of iron (specific heat: 0.45 kJ/kg.K) with a mass of 20 kg is heated from its initial temperature of 10oC to a final temperature of 200oC by keeping it in thermal contact with a thermal energy reservoir (TER) at 300oC. All other faces of the block are completely insulated. Determine the amount of
(a) Heat.
(b) Entropy transfer from the reservoir.
(c) Also calculate the entropy generated in the system's universe due to this heat transfer.
