â the second law of thermodynamicsâ
What Ep means: The Second Law of Thermodynamics is a fundamental law based on the following elementary macroscopic observations:

â˘ work can be fully converted into heat, but conversely, heat can never be fully converted into work (this fact was particularly discovered during the development of the steam engine)
