Explain the concept of 'Entropy in Thermodynamics' as if I were a 12-year-old with no background in physics. Use the Feynman Technique: use simple language, avoid jargon, and rely on analogies involving everyday objects (like a messy room or a deck of cards). Break the explanation down into: 1. What it is, 2. How it works, 3. Why it matters. Conclude with a simple analogy that summarizes the Second Law of Thermodynamics.
