SUMMARY
The heat engine operates between a hot reservoir of steam at 100°C and a cold reservoir of ice at 0°C. In 1.4 hours, 12 kg of steam condenses and 60 kg of ice melts. The power output can be calculated using the equations for efficiency and work output, specifically Wout = Qh - Qc, where Qh is the heat extracted from the hot reservoir and Qc is the heat released to the cold reservoir. Understanding the specific heat capacities and the latent heat of fusion for ice and vaporization for steam is essential for determining the power output accurately.
