The document discusses the first law of thermodynamics, which states that energy can be transformed from one form to another but cannot be created or destroyed. It applies to both closed and open systems. The first law provides an equation for closed systems undergoing a change of state, where the heat (Q) added to the system minus the work (W) done by the system equals the change (δE) in the system's internal energy.
