Document Summary
A heat engine exhausts 3000j of heat while performing 1500 j of useful work. An electrical power plant manages to send 88% of the heat produced in the burning of fossil fuel into the water to steam conversion. Of the heat carried by the steam, 40% is converted to the mechanical energy of the spinning turbine. Which of the following choices best describes the overall efficiency of the heat to work conversion in the plant (as a percentage)? less than 40% According to the second law of thermodynamics, which of the following applies to the heat received from a high temperature reservoir by a heat engine operating in a complete cycle? cannot be completely converted to work. A heat engine receives 6000j of heat from its combustion process and loses. A turbine takes in 1000 k steam and exhausts the steam at a temperature of.
