SUMMARY
The power output of the heat engine is determined by the heat transfer from the hot reservoir to the cold reservoir. In this scenario, steam at 100°C condenses to water, while ice at 0°C melts. The relevant equation for calculating power output is W = Q_in - Q_out. To find Q_in and Q_out, one must utilize the latent heats of vaporization and fusion for water, specifically the latent heat of vaporization (2260 kJ/kg) for steam and the latent heat of fusion (334 kJ/kg) for ice.
