System surrounding in Thermodynamics

System and surrounding

System:

                    Quantity of mater or region in space chosen for study is called system.

Surrounding:

                    Mass or reign out side of the system is called surrounding.

Boundary:

                 Boundary is a real and imaginary wall which separates system and Surrounding

It may be Fixed or moveable.

We take it ideally

Types of system:

Closed System:

  In closed system only heat is transfer and no mass is transfer called closed system.

   For example :  in piston only heat is transfer

Open system:

In open system and heat both are transfer is called closed system

Thermodynamic

Thermodynamics

Thermo        means       Heat

Dynamics     means       movement

It deals which temperature and its Effect upon body under goes various thermal changes

·       It tell us how much energy transform

·       How much work is done

·       What is the final state of system

 

Fundamental properties of thermodynamic:

There three fundamental properties of thermodynamic these are:

1.     Temperature      T

2.     Pressure              P

3.     Volume              V

Applications of thermodynamics

Thermodynamic is used in every field because every field

For example

·       in our daily life this phenomena in human body temperature and room temperature

Thermodynamic have a great use industries

·       Every industry must have a boiler and in these boiler we produce super steam which is free of moisture

·       And in pressure cooker is phenomena is used for quick cooking

Thermodynamic in Engineering

It is also used in engineering like in transformers and Generator

Transformer:

 In transformer when current is flow from winding the heat is produce to cool the transformer we used oil which transfer heat from winding to cooling tube

Due to heat gas is produce in oil and the pressure increase in the transformer which is danger

Generator:

            In industrial Generator we used Hydrogen gas for the cooling of the generator which is air tide seal and generator pressure also increase
