The basic theory of thermodynamics is treated in the book using ideal
gas as an example. A clear explanation for the quantity entropy is given
in the book. Analytic formulas for the mutual functional dependence of
the quantities volume, pressure, temperature and entropy are given in
the book in the case of an ideal gas. A thorough treatment of ideal gas
thermodynamic processes is presented in the book. In a process two
quantities are given as functions of time and other quantities are
calculated as functions of time. I hope that the thorough treatment
helps especially those people (for example students) who take their
first steps in learning thermodynamics. The book includes a list of a
computer program that calculates basic thermodynamic processes for an
ideal gas. An example calculation for every process is presented in the
book - input file is given and the result is presented as curves. Every
curve is given a thorough description.
