Which outcome results when a heat engine's hot reservoir undergoes solidification?

💡 Explanation

Mechanical work diminishes because solidification releases latent heat, causing 'thermodynamic irreversibility' where energy becomes less useful, therefore the output lessens, rather than entropy decreasing or efficiency increasing due to lost potential for phase transition driven work.
