This module have 12 elements, described below. With a description of
each one, its data and its number of equations. In parentheses are
shown the units used be FisicaLab (if no conversion factors are used)
in cases where may be doubt. The elements Adiabatic process,
Isochoric process, Isothermal process, Isobaric process, Heat
machine, Refrigerator and Heat pump support the application of heat
elements (Heat applied and Heat extracted) and work. These elements
are applied to other element placing them in one of the eight cells
around.
