Q3. First law of T.D
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 change forms (e.g. from potential to kinetic)

• Heat and work are two ways energy can be transferred

• Mathematically expressed as: ΔU = Q - W
