Thermodynamics Laws

Subject: Chemistry

Book: General Chemistry

The laws of thermodynamics govern energy transfer and transformation. The first law states energy is conserved. The second law relates to entropy, indicating that total entropy always increases in a spontaneous process. The third law states that the entropy of a perfect crystal at absolute zero is zero. These principles underlie all chemical and physical processes, guiding efficiency in engines, refrigerators, and more.
