First Law of Thermodynamics. There exists for every system a property called energy, . The system energy can be considered as a sum of internal energy, kinetic energy, potential energy, and chemical energy. Like the Zeroth Law, which defined a useful property, ``temperature,'' the First Law defines a useful property called ``energy.''.

WebFor a steady-flow process, the total energy content of a control volume remains constant. That is, dE system /dt = 0. Thus, the amount of energy entering a control volume in all forms (heat, work, mass transfer) must be equal to the amount of energy leaving it for a steady-flow process. In an equation format, it is (Rate of net energy transfer ...
