First, the establishment of the second law of thermodynamics In the production practice, the Frenchman Babben invented the first steam engine, and later the steam engine improved by Watt was widely used in the 19th century. The problem of improving the heat engine efficiency became the field of production at that time. The important issue. 1 In the 20th century in the 20th century, the French engineer Carnot (S. Carnot, 1793-1832) studied theoretically the efficiency of heat engines.
