Explain Kelvin-Planck statement and Clausius statement
Kelvin-Planck statement: "No process is possible whose sole result is the absorption of heat from a reservoir and the total conversion of the heat into work"
Clausius statement: "No process is possible whose sole result is the transfer of heat from a colder object to a hotter object".
* It can be prove that the two statements above are completely equal.
