Q4. Thermodynamic laws
Ans. 
Thermodynamic laws govern the behavior of energy in systems.
• The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.

• The second law of thermodynamics states that the entropy of an isolated system always increases over time.

• The third law of thermodynamics states that as the temperature approaches absolute zero, the entropy of a system approaches a minimum value.
