FUNDAMENTALS OF THERMODYNAMICS
Introduction, Review of basic definitions:
Zeroth law of Thermodynamics, Macro and Microscopic Approach, State Postulate, State, Path, Process and Cycles, Point function and Path function, quasi static process, Equilibrium, Temperature (concepts, scales, international fixed points and measurement of temperature), Constant volume gas thermometer and constant pressure gas thermometer, mercury in glass thermometer.
THERMODYNAMICS
Greek word
“Therme” Means Heat.
“Dynamics” Mean Power.
Together convert heat into power
THERMODYNAMICS DEFINATION
It is a branch of physical science which deals with energy transfer and effect of energy transfer on properties of substance.
Thermodynamics deals with energy conversion, energy exchange and the direction of exchange.
LAWS OF THERMODYNAMICS
0th Law ⇒ Defines Temperature (T)
1st Law ⇒ Defines Energy (U)
2nd Law ⇒ Defines Entropy (S)
3rd Law ⇒ Gives Numerical Value to Entropy
These laws are UNIVERSALLY VALID, they cannot be circumvented.
The study of thermodynamics is the basis of such fields as steam power plants, IC Engines, Gas dynamics and aerodynamics, fluid mechanics, Refrigeration and Air conditioning and heat transfer.
REVIEW OF THERMODYNAMIC DEFINITION
SYSTEM : Quantity of matter or region in space, chosen for study.
SURROUNDINGS : Mass or region outside the SYSTEM.
BOUNDARY : Real / Imaginary surface that separates the SYSTEM from SURROUNDINGS.
BOUNDARY :
|----Fixed / Movable
