Chapter XVI The Second Law of Thermodynamics
The first law of thermodynamics gives the quantiative relations between
the internal energy of a system and the quantities of heat and work that
the system exchange with surroundings. It express the conservation of
energy.
The first law of thermodynamics is true, but not enough ! Why ?
Many thermodynamic processes which don’t violate the 1st
law,
but don’t happen in nature !
