A power plant operates at a 32.0% efficiency during the summer when the seawater used for cooling is at 20.0°C. The plant uses 350°C steam to drive turbines. If the plant’s efficiency changes in the same proportion as the ideal efficiency, what would be the plant’s efficiency in the winter, when the seawater is at 10.0°C?
