1,The second law of thermodynamics proves that isotherms and adiabatic lines cannot intersect at two points.

2. Water is at the triple point, and the working fluid includes water, ice, and water vapor. Adiabatic compression working fluid, water vapor liquefaction releases heat, ice melts into water, absorbs heat, and the temperature remains unchanged.

3. The above discussion indicates that isotherms and adiabatic lines are collinear and have countless intersection points,

4. The second law of thermodynamics is inconsistent with experiments and is incorrect.
