Work & Heat
In mechanics, work is dened as the integral of a force over a
displacement. In mathematical form, work (W) is a scalar
quantity dened according to:

Some Observations in Work & Heat Conversions
Heat Engines & Second Law of Thermodynamics
Work can always be converted to heat
directly and completely, but the reverse
is not true.

Steady-State, Steady Flow (SSSF) Processes
Assumptions:
Steady-State, Steady Flow (SSSF) Processes - I
Control volume does not move relative to the coordinate frame.
State of the mass at each point in the control volume does not
vary with time.

Reversibility
A process commencing from and initial equilibrium state is called
reversible (or totally reversible) if at any time during the process
both the system and their environment with which it interacts can be
returned to their initial states.

Entropy
Consequences of Second Law of Thermodynamics
Second Law of Thermodynamics: Entropy
If a system is taken through a cycle and produces net work, it
must be exchanging heat with at least two reservoirs at 2 dierent
temperatures.

A thermodynamic system is simply any object, quantity of
matter, or region of space that has been selected for study.
Everything that is not part of the system is referred to as
