Q5. What are the principles of thermodynamics?
Ans. 
Thermodynamics principles govern energy transfer, heat, and work in physical systems, crucial for engineering applications.
• First Law: Energy cannot be created or destroyed, only transformed (e.g., a steam engine converts heat to mechanical work).

• Second Law: Entropy of an isolated system always increases (e.g., heat flows from hot to cold bodies).

• Third Law: As temperature approaches absolute zero, entropy approaches a c...read more
