The Second Law of Thermodynamics is a fundamental principle governing heat transfer and energy efficiency. It introduces entropy, a measure of disorder, indicating that energy transformations are not completely efficient, as some energy is lost as heat. This law also explains the irreversibility of natural processes and sets limits on the performance of heat engines and refrigerators, highlighting the universal trend of increasing entropy.
