Thermodynamics

Thermodynamics:
Branch of science, deals with energy transfer, effect on state or condition of a system & physical properties(Pressure, Volume and Temperature) of substances by this transformation.
Interaction of system & surroundings, energy and its transformation.
James Joule-Mechanical WD can be converted into heat energy.
James Watt-First steam Engine
Energy may includes various forms, BUT MAINLY DEALS with HEAT & WORK.
Feasibility of process and concept of equilibrium process Es-Energy, Entropy and Equilibrium.
Utilization of Energy:
a) Power Producing- IC engine, Turbine & Power Plant etc
b) Power Consuming- Fan, Blower, Compressor, Refrigerator & Air conditioners etc
c) Chemical Processing Unit & Direct Energy Conversion Devices.

Thermodynamics is based on: Like other sciences
--Experimental results, observations and common experiences
--There is no proof of laws of thermodynamics & Zeroth law
--laws lay down- general restrictions within which energy transformation occur.
