This document discusses the fundamentals of thermodynamics. It introduces thermodynamics as the branch of engineering science dealing with the movement of fluids through the application of heat. It then defines thermodynamics processes as the successive states a system passes through during a change in state. The document goes on to summarize the four main laws of thermodynamics: zero law regarding systems in thermal equilibrium, first law regarding the conservation of energy, second law regarding heat flow from hot to cold bodies, and limitations of the second law such as the impossibility of converting all heat into work.
10. This Is Dependent Of Mass Of The
System
Example:-Energy
This Is Independent Of Mass Of The
System
11. THERMODYNAMICS PROCESS
• When A System Change Its States Then The
Path Of Successive State Through Which The
System Passed Is Known As Thermodynamics
Process.
12. Zeroth Law Of Thermo Dynamics:-
This Law State That If Two System Are Separately
In Thermodynamics Equilibrium With The Third
System Then Two System Will Be In
Thermodynamic Equilibrium.
13. According To The 1st Law Of Thermodynamic
Energy Can Neither Be Created Nor Can Be
Destroy .Its Can Be Transfer One To Another
Place.
• Its Dose Not Specific The Direction Of Process Under
Consideration.
• The Heat Energy And Mechanical Work Are Mutually
Convertible i.e. It Is Nothing But A 100% Efficient
Machine But Its Impossible.
14. Its State That Heat Energy Flows From A Body At
Higher Temperature To lower Temperature. But It Is
Impossible For Heat To Flow From A Body At Lower
Temperature To A Body At Higher Temperature.
15. LAWS OF THERMODYNAMICS
LIMITATION OF 2ND LAW OFTHERMODYNAMICS:-
1. Kelvin Planck Statement:-
It Is Impossible To Constrict An Engine Which
Can Converted All The Heat Supplied Into
Work.
16. LAWS OF THERMODYNAMICS
It Is Impossible To Contracted A System Which
Transfer Heat From Cold Body To Hot Body With
Out Work done By Surrounding.
