Energy may exist in different forms. It can be light energy, thermal energy, potential energy, kinetic energy, chemical energy, nuclear energy, etc. Every physical matter (or body or thermodynamic system) intrinsically possesses certain amount of energy in one form or another. Such energy can be converted from one form to another for storing it within the same body. It can also be transferred from one body to another with or
Thermodynamic system is defined as a definite quantity of matter or a region in space upon which attention is concentrated for the analysis of a problem. Everything in this universe external to the system is called surroundings. The system is separated from the surroundings by the system boundary. Every interaction between the system and surroundings occurs across the boundary. There are two distinct ways of interaction between system and surroundings,
Thermodynamic system refers to a definite quantity of matter or a specific region in space upon which attention is concentrated for the analysis of a problem. Each thermodynamic system has certain characteristics by which its conditions can be described. Such characteristics are known as thermodynamic properties. Properties are always macroscopic in nature (i.e. observable or sensible with simple instruments). Properties are also point functions (i.e. property has a definite value
For the analysis of any thermodynamic problem, the concerned matter or a region is considered as the system. By definition, thermodynamic system is defined as a definite quantity of matter or a region in space upon which the attention is focused for the analysis of a problem. Everything in the entire universe external to this system is called the surroundings. The system is separated from the surroundings by a boundary.
