Heat and Thermodynamics

Questions

1. Give the enunciation of the second law of thermodynamics as given by Clausius as well as by Kelvin. Show that the two actually mean the same thing.
2. Explain the terms: reversible process and reversible cycle. Describe Carnot's cycle. Is the efficiency of the Carnot's cycle dependent on the nature of the working substance?
3. Describe a Carnot's engine. Draw the p-v indicator diagram for a cycle of its operations between two given temperatures and deduce from it the thermal efficiency of the engine.
4. State and explain the significance of the second law of thermodynamics. Show that the efficiency of a reversible engine is maximum.
5. Show that no engine can be more efficient than the reversible Carnot's engine.
6. How did Kelvin arrive at the absolute ...
