In principle, we could measure this energy, by summing all of the kinetic (and potential) energies of the molecules. CHAPTER 10 HEAT AND THERMODYNAMICS Thermodynamics is the study of heat and work. It is a science, and more importantly an engineering tool, that is necessary for describing the performance of propulsion systems, When a hot object meets a cool object, energy, is transferred to the cool object because the hot object’s molecules or atoms are bumping, into those of the cool object, transferring kinetic energy; this transfer of energy is called, heat. Robert B. Griffiths, a specialist in thermodynamics and statistical mechanics at the Carnegie Mellon University, commented that both editions of this book presents clearly and concisely the core of thermodynamics within the first eight chapters. While internal energy refers to the total energy of all the molecules within the object, heat is the amount of energy flowing from one body to another spontaneously due to their temperature difference.Heat is a form of energy, but it is energy in transit.Heat is not a property of a system. This chapter will explore these laws as well as many applications and concepts associated with them. It is the heat capacity of 1 g of substance of the system.
