There are
just two ways that energy is transferred _______(1) work or heat. We often use the words “work” and “heat”____(2) they are forms of energy. Some thermodynamic
textbooks, however, say that work and heat are processes or methods____(3) energy transfer, not forms of energy.
Will you agree that
would be the clearer way to refer ____(4) those two processes? Really, think about it for
a bit. It is energy that is transferred or changed. The process____(5) this occurs is either by work or by heat (not by a hook or by a crook). In this
context, they are processes or methods of energy change, not types of energy. An example: A man is floating
in water after falling out of a boat. The water temperature is 0*C. Because
the water temperature____(6) than the man's body temperature of 38* C, and
because water is such a good ____(7) for heat flow, energy as heat will flow rapidly from his body into the water.
In just a few miserable minutes the man's body temperature will start to drop,
and the water around him will be____(8) a little bit. Scientifically speaking, by the process of heat flow energy is being transferred from his body to the surrounding water. It was internal energy that was
transferred, not heat. We usually say he is losing heat. But what he is really _________(9) is internal energy. Internal energy is the word that is more correctly used in thermodynamics
to describe the microscopic forces and movements that are often____(10) heat.
