Clausius
Statement Example
Example of Clausius statement is
a refrigerator with COP (coefficient of
performance) equal to infinity which is impossible.
We have read about heat engines that
convert heat energy into work and its application in various fields of
thermodynamics. Can we think of a device that is the opposite of a heat engine,
i.e. a device that helps in the conversion of work into heat? In this section,
we will learn about the refrigerator and heat pump that works on the opposite
principle of a heat engine.
Refrigerator
It states that “It
is impossible to construct a device which operates on a cycle and produces no
other effect than the transfer of heat from a single body in order to produce
work.” This means that it is impossible to construct an engine
whose sole purpose is to convert the heat from a high-temperature
source/reservoir into an equal amount of work. This is a special case of the
second law of thermodynamics.
