Thermodynamic Properties of A System    Any characteristic of a system is called a property. Every system has certain characteristics by which its physical condition may be described, e.g., volume, temperature, pressure, etc. The list can be extended to include velocity, viscosity, thermal conductivity, modulus of elasticity, coefficient of thermal expansion, resistivity and elevation, etc. The salient features of a thermodynamic property are the following:   (a) A property is a measurable characteristic, describing the state of a system.   (b) It has a definite value when the system is in a particular state. (c) It also helps to distinguish one system from another.  (d) The magnitude of a property depends on the state of the system, and it is independent of the path or route followed by a system during a process. (e) A property is an exact differential.   Properties may be classified as    1. Intrinsic and extrinsic properties according...

Thermodynamics  is a branch of physics dealing with matter and conversion of energy, conversion of energy into heat and work in particular. Each object of interest in  engineering  contains matter, therefore,  thermodynamics  is usually included or indirectly involved in the analysis of almost all  engineering  problems. THERMODYNAMIC SYSTEM :- A thermodynamic system, or simply a system, is defined as a certain quantity of matter or a prescribed region in space considered for thermodynamic study. The region outside the system is called the surroundings or environment. The real or imaginary surface that separates the system from its surroundings is called the boundary. The boundary of the system may be fixed or movable. The system and its surroundings constitute the universe.  TYPES of  SYSTEMS :- The thermodynamic systems can be classified as  1. Closed and open systems  2. Homogeneous and heterogeneous systems  1)  CLOSED...
