... This is called “The First Law of Thermodynamics”. Aside: Actually the First Law of Thermodynamics is this: “heat added plus work done equals change in energy” or Q + W = U . (Q is the symbol for heat). In this chapter we won’t consider adding heat to a system (like holding a flame under it), so Q = ...
