Laws of Thermodynamics
Four laws governing heat, energy, entropy and absolute zero โ the backbone of energy science
Germany/UK ๐ 1850 Physics
Key Facts
- 1
0th Law: if A=B and B=C in temperature, then A=C โ defines thermal equilibrium and thermometers
- 2
1st Law (Conservation of Energy): energy cannot be created or destroyed, only converted
- 3
2nd Law: entropy always increases โ heat flows from hot to cold; you can't have a 100% efficient engine
๐ฌ Did you know? "Entropy always increases" โ the Second Law explains why ice melts but never spontaneously re-freezes, and why time moves forward
