Second Law of Thermodynamics
- Clausius statement
- No process is possible whose sole result is the transfer of heat from a colder to a hotter body.
- Kelvin-Planck statement
- No process is possible whose sole result is the absorption of heat from a reservoir and the conversion of all of this heat into work.
- Carnot's theorems:
- i)No engine can be more efficient than a reversible engine working between the same limits of temperature.
- ii)All reversible engines working between the same two limits of temperature have the same efficiency.
- ii)All reversible engines working between the same two limits of temperature have the same efficiency.
