They are intensive those that do not depend on the amount of matter of the system (pressure, temperature, composition). The system can be the finite quantity of matter or a selected region in the space. A system may be defined in different ways: Anything under consideration or under experiment in the laboratory or elsewhere is called a system. The thermodynamic stateof a system is defined by specifying values of a set of measurable propertiessufficient to determine all other properties. View [Enrico_Fermi]_Thermodynamics(z-lib.org).pdf from ENGINEERIN 2223 at NED University of Engineering & Technology, Karachi. Within thermodynamics, a physical property is any property that is measurable, and whose value describes a state of a physical system. The word microscopic means something like so small that it can only be seen with the use of microscope while macroscopic means either to something that can be seen with the naked eye or large in scale. For fluid systems, typical properties are pressure, volume and temperature. It has been discussed that state variables are defined only when the thermodynamic system is in equilibrium with the surrounding. Examples: temperature, refractive index, density, surface tension, specific heat, freezing point, and boiling point. Properties that are dependent on mass are called extensive properties and its value for the overall system is the summation of its values for the parts into which the system is divided.  Some familiar properties are pressure P, temperature … Within this set of properties we have all the specific values ​​as specific internal energy, specific enthalpy, specific entropy, temperature, pressure, sp… Accurate thermophysical properties are available for several fluids. Classical thermodynamics deals with systems in equilibrium. Open system: The system in which the transfer of mass as well as energy can take place across its boundary is called as an open system. A thermodynamic system is defined as the space, region, or quantity of matter (Finite amount, measurable in kg) in which our study is focused. Thermodynamics is the study of changes that occur in some part of the universe we designate as the system; everything else is the surroundings. These properties will be further applied to energy systems and finally to thermal or nuclear power plants. Thermodynamic Properties: Every system has certain characteristics such as Pressure, Volume, Temperature, Density, Internal Energy. Pressure and temperature are intensive properties. E.g. Before going to move on the definition of Surrounding, Boundary, Universe first considers a system as shown in the figure: Everything external to the system is called Surrounding. Mass, volume, internal energy, heat contents, free energy, entropy, and heat capacity are all extensive properties. In this chapter after short review of thermodynamic laws, nanothermodynamic and thermodynamic properties of nanosized systems are presented. For a system composed of a number N of mass-points, this re- quires the knowledge of 6N variables. More complex systems may require the specification of more unusual properties. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. As can be seen from the definition, the boundary can be fixed or moving.A system in which matter crosses the boundary is called an open system. Furthermore the properties can be either Extensive or Intensive (or Specific). I Thermodynamic Systems and Properties. by which its physical condition may be described. Properties of a system in thermodynamics, about Properties of a system in thermodynamics. The intensive ones do not depend on the size of the system. Our goal here will be to introduce thermodynamic properties, that are used in engineering thermodynamics.These properties will be further applied to energy systems and finally to thermal or nuclear power plants. In this article, I am going to explain about the Macroscopic and Microscopic approach of a thermodynamic system in a detailed manner.
