Introduction
Thermodynamics
Thermodynamics is the science devoted to the study of energy, its transformations, and its
relation to the status of matter.
energy the first law (conservation of energy)
entropy the second law (quality of energy)
every naturally occurring transformation of energy is panied
somewhere by a loss in the availability of energy for future performance of
work
System and Surroundings
System: an object, any quantity of matter, any region of space, etc. selected for study
Surroundings: the rest
Basic system types: Closed system (control mass) and Open system (control volume)
Property, State, Process and Equilibrium
A property is the observable characteristic of a system such as temperature, pressure and
density.
A state is the condition of the system defined by properties.
A process is transformation of the system from one state to another.
A thermodynamic cycle is a process that begins and ends at the same state.
