The short answer: German physicist Rudolf Clausius discovered the second law of thermodynamics during the year 1850.
- During the year 1850, Rudolf Clausius discovered the second law of thermodynamics as;
“Heat can not itself flow from colder body to a hotter body.”
This is known as Clausius statement in thermodynamics.
- Also in 19th century only, the another statement of second law was proposed by Lord Kelvin and Planck.
This statement is known as Kelvin-Plank’s statement which is mentioned below;
“It is impossible to construct a device (operating in a cycle) which works on a single heat source and converts all of its heat completely in to work”
- Later in 1865, Rudolf Clausius discovered the entropy statement of the second law of thermodynamics as;
“The entropy of the universe tends to a maximum”
