The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only converted from one form to another. Mathematically, this is expressed as:

where ΔE is the change in energy, Q is the heat added to the system, and W is the work done on the system. thermodynamics cengel ppt
