WebEnergy Transfer. The next topic concerns how the human body exchanges energy (or heat) with its surroundings. This will include how the body responds to both hot and cold temperatures AND how humidity and winds factor into the heat exchange. This will lead us to the concepts of wind chill factor and heat index. We start with a few basics. Web(a) Heat transfer occurs spontaneously from hot to cold, but not from cold to hot. (b) The brakes of this car convert its kinetic energy to increase their internal energy (temperature), and heat transfers this energy to the environment. The reverse process is impossible.
