Fundamental Laws
• Zeroth Law: Defines temperature equilibrium
• First Law: Energy cannot be created or destroyed
• Second Law: Entropy always increases
• Third Law: Absolute zero is unattainable
Key Concepts
• Enthalpy (H): Total heat content
• Entropy (S): Measure of disorder
• Gibbs Free Energy: Predicts spontaneity
• Heat Capacity: Temperature change per heat
Important Constants:
• Gas Constant (R): 8.314 J/mol·K
• Boltzmann Constant (k): 1.381×10⁻²³ J/K
• Avogadro's Number: 6.022×10²³ mol⁻¹
• Stefan-Boltzmann Constant: 5.67×10⁻⁸ W/m²K⁴
Fascinating Thermodynamics Facts:
1. Sun's Power: Outputs ~3.8×10²⁶ W (equivalent to 100 billion 1-megaton bombs/sec)
2. Absolute Zero: Theoretical limit of -273.15°C where molecular motion stops
3. Human Body: Radiates ~100W of heat at rest (like a bright lightbulb)
4. Max Efficiency: Carnot limit = 1 - (Tₑ/Tₕ) sets fundamental efficiency cap
5. Black Holes: Have entropy proportional to their surface area
6. Refrigerators: Violate 2nd Law? No, they use work to move heat "uphill"
7. Universe's Fate: Heat death predicted when maximum entropy is reached
8. DNA Replication: Driven by thermodynamics and entropy changes

⚠️ Scientific Note: Thermodynamics governs energy flow in all physical systems, from microscopic chemical reactions to stellar fusion. These calculations provide approximate values for educational purposes. Real-world applications require consideration of additional factors like phase changes, non-ideal behavior, and system boundaries.
