Table of Content (toc) ​ What is property of thermodynamic system? • A property of a system is an observable characteristic of the system. • The quantities which define the state of the system are called properties. • Whose value must be independent of the process • The property is a point function ​ Classification of properties Thermodynamic properties are generally divided into two classes 1. Intensive properties: These are independent of mass of the substance Eg: pressure, temperature, density, specific gravity, specific volume, surface tension, thermal conductivity etc. ​ 2. Extensive properties: These are dependent on mass of the substance Examples: mass, weight, enthalpy, entropy, internal energy etc. ​ State: • State of the system is a condition and is identified through certain observable properties such as pressure, volume, temperature, density etc. • Two independent properties are sufficient to represent the state. ​Path: • The path is the series of states thr

Thermodynamics         Thermodynamics is the science, which deals with the  relations between heat, work and those properties of  substances which are connected with heat and work. Applications Of Thermodynamics In automobile engines heat energy of fuel is converted into work energy which drives the vehicles. Conversion of heat into work depends on the principles of thermodynamics. The working of rocket and jet engines depends on the              principles of thermodynamics. Refrigeration and air conditioning is used to maintain required temperature. Thermodynamic System Thermodynamic system or simply system is a region   in space containing a certain quantity of matter upon whih  attention is focused for study. This system may be quantity of steam, mixture of      vapour and gas or an I.C engine cylinder and its      contents.   System is enclosed by a boundary. Boundary         separates the system from the surroundings.        The boundary may b
