Q2. First law of thermodynamics
Ans. 
The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.
• Energy can be transferred between systems or converted from one form to another.

• The total energy in a closed 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.

• Example: When a gas is compr...read more
