FIRST LAW OF THERMODYNAMICS Thermodynamics Summary The important information from this chapter is summarized below. First Law of Thermodynamics Summary • The  First  Law  of  Thermodynamics  states  that  energy  can  neither  be created nor destroyed, only altered in form. • In analyzing an open system using the First Law of Thermodynamics, the energy into the system is equal to the energy leaving the system. • If the fluid passes through various processes and then eventually returns to the same state it began with, the system is said to have undergone a cyclic process.   The first law is used to analyze a cyclic process. • The  energy entering any component is equal  to the energy leaving that component at steady state. • The amount of energy transferred across a heat exchanger is dependent upon the temperature of the fluid entering the heat exchanger from both sides and the flow rates of thse fluids. • A T-s diagram can be used to represent thermodynamic processes.
