In this chapter, we will study thermal processes. Thermodynamics is the science of heat and hotness, of how bodies and other physical systems respond to heat, of how heat can be used to drive other processes, and how heat is produced.
Heat can be transported by conduction, convection, and radiation. An interesting type of coupling of processes can be demonstrated in thermoelectric phenomena.
Heat behaves in many ways like electricity or like fluids. This allows us to make use of analogical reasoning so we can get to know thermal processes more easily.
