what is the reason of hat and work is not conserved energy?
Answer Posted / Ravi Kishor
The First Law of Thermodynamics, also known as the Law of Energy Conservation, states that energy cannot be created or destroyed, only transferred or changed from one form to another. However, in real-world systems, there are several reasons why neither heat nor work is conserved: 1) Frictional losses (internal and external), 2) Heat transfer across a system boundary, 3) Work done by the system on its surroundings, and 4) Work done by the surroundings on the system. These processes result in a decrease of energy within the system, making it impossible to conserve both heat and work.
