Here are the four laws of thermodynamics:
1. Zeroth Law: This law states that if two systems are each in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other. This essentially defines the concept of temperature.
2. First Law: This law states that energy cannot be created or destroyed, only transferred or transformed. It's essentially the law of conservation of energy.
3. Second Law: This law states that the entropy of a closed system always increases over time. Essentially, things tend towards disorder.
4. Third Law: This law states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. It implies that it's impossible to reach absolute zero.
Let me know if you'd like a more detailed explanation of any of these laws!
