Q1. First law of thermodynamics
Ans. 
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.
• Energy is conserved in a closed system

• Energy can be transferred between different forms (e.g. heat, work)

• The total energy of a system remains constant

• Mathematically expressed as: ΔU = Q - W, where ΔU is the change in internal energy, Q is heat added to the system, and W is work done by the system
