V3- Thermodynamic System and Properties

 

What is system, boundary and sorrounding in thermodynamics?


System: The system is defined as a part of the universe that is chosen for the thermodynamic study. 

Surrounding: The region outside the system is known as surrounding.

Boundary: The actual or imaginary line which separates the system and surrounding is known as boundary.

What are different types of thermodyanmic system?

There  are three types of thermodynamic system:

1-Open System

2-Closed System

3-Isolated System


An open system can exchange matter and energy. 

A closed system can exchange energy (e.g. heat) but not matter.

An isolated system cannot exchange energy or matter.

Explain control volume...

Control volume system is basically defined as one fixed area in space upon which the study will be focused and mass or matter will enter in to the system and will leave the system continuously.

Difference between control volume and open system..

The control volume is that part of the system that is under consideration; the part to be modeled. An open system simply means mass can enter and exit the system


What are thermodynamic properties? Explain Types of thermodynamic properties.

Thermodynamic properties are defined as characteristic features of a system capable of specifying the system’s state.

Types of thermodynamic properties

Intensive properties-   Are independent of amount of mass

                       For example- Temperature,Pressure,Density,etc

Extensive Properties-   Varies with the mass

                       For example- Mass,Volume,Energy,Enthalpy,etc

Specific Properties-  An extensive property expressed per unit mass of system

                       For example- Specific energy,Specific entropy,etc

Molar Properties-  The ratio of entensive properties to mole number

V2-Concept of Continuum and Macroscopic Approach

  For reference i am using links and book named (Sonntag, R. E., Borgnakke, C., & Wylen, G. J. V. Fundamentals of thermodynamics: Wiley.) What is thermodynamics explain? Thermodynamics is the study of the relations between heat, work, temperature, and energy . In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. TRL1-     https://www.britannica.com/science/thermodynamics CONCEPT OF CONTINUUM When we study thermodynamics we usually focus on studying the behaviour of materials by ignoring its particulate nature.    In order to do that we have introduced the concept of continuum  According to this concept a continuum is an area that can keep being divided and divided infinitely; no individual particles.  It is a simplification that makes it possible to investigate the movement of matter on scales larger than the distances between particles.   For example - When asking questions s...
