Below are the major uses of second law of thermodynamics EXCEPT
The second law may be used to identify the direction of processes.
The second law also asserts that energy has quantity.
The second law provides the necessary means to determine the quality as well as the degree of degradation of energy during a process.
The second law of thermodynamics is also used in determining the theoretical limits for the performance of commonly used engineering systems
