a.) A particular car engine operates between temperatures of 400°C (inside the cylinders of the engine) and 20°C (the temperature of the surroundings). Given these two temperatures, what is the maximum possible efficiency the car can have? (Note that actual car engine efficiencies are in the 20-25% range.) _______ % b.) A particular car engine operates between temperatures of 400°C (inside the cylinders of the engine) and 20°C (the temperature of the surroundings). If the car was somehow able to...

A heat engine operates at a temperature of 650 K. The work output is used to drive a pile driver, which is a machine that picks things up and drops them. Heat is then exhausted into the atmosphere, which has a temperature of 300 K. a. What is the ideal efficiency of this engine? b. The engine drives a 1200 kg weight by lifting it 50 m in 2:5 sec. What is the engine’s power output? c. If the engine...
