Second law of thermodynamics

{
  "id": "MLC-T-MET-008734",
  "term": "Second law of thermodynamics",
  "field": "Meteorology and atmospheric science",
  "definition": "A fundamental principle stating that the total entropy of an isolated system can only increase over time, or remain constant in ideal cases. This law dictates the direction of spontaneous processes, such as heat flowing from warmer to colder regions. In atmospheric science, it explains why energy gradients tend to dissipate and why perpetual motion machines are impossible.",
