Thermodynamics is a part of science which is related to heat, temperature, and energy. It is concerned with various forms of energy and its mutual conversion. The Thermodynamic behavior of different quantities or matter is controlled by 4 laws of thermodynamics. In this universe, there is always a relation between any matter and energy. Thermodynamics is applicable in a wide range of Science, Technology and Engineering world.
The motive of studying thermodynamics is to understand various forms of energy and develop the efficient energy systems.
Properties are categorized into two parts "Intensive properties and extensive properties"
a locii. that locii will be known as Thermodynamic Path.
To get a system in Thermodynamic Equilibrium it should be in equilibrium mechanically, thermally and chemically.

Important terms related to thermodynamics
There are some important terms related to thermodynamics which is often used during thermodynamic analysis.Thermodynamic Properties
Properties are the parameters which describe the nature and characteristics of a system. these parameters are used to define the thermodynamic system and its behavior. Some examples of thermodynamic properties are pressure, volume, temperature, viscosity etc.Properties are categorized into two parts "Intensive properties and extensive properties"
Intensive properties
Intensive properties are those which are independent of the mass of the system in which matter is enclosed. As the properties are independent of mass, the properties will have identical value at every point of the system. Examples of intensive properties are pressure temperature etc.Extensive properties
Extensive properties are dependable on the mass of the system these properties do not have the same value in the whole system. Examples of these properties are volume, viscosity, energy etc.Thermodynamic State
State of a system can be defined as a certain position or condition in which properties of the system will have certain quantitative values. These Values defines a specific state. Changing these values will lead to the different state of the system. this change is called 'change of state'.Thermodynamic Process
Due to the energy and mass transfers from the system and to the system, change of state takes place. This changing of the state is called process. for example, heating of a gas in a vessel can lead to change in pressure and temperature viscosity etc. In such ways, properties of the system can be altered and a thermodynamic process is completed.Thermodynamic Path
A path is something when the change of state happens repeatedly and series of the process occurs. In the system, this series of process can be traced bya locii. that locii will be known as Thermodynamic Path.
Thermodynamic cycle
When a system undergoes to several processes but at the last, it gains its initial state from where the sequence of processes started, then the system is said to be completed a cycle. all in all the initial and final state will be same in a cycle. the cycle will have a closed loop path in the thermodynamic system.Thermodynamic equilibrium
When the system does not undergo in a change of state even when the external efforts are applied, then the system is said to be in Thermodynamic EquilibriumTo get a system in Thermodynamic Equilibrium it should be in equilibrium mechanically, thermally and chemically.
these are some important terms and parameters of thermodynamics. Although, thermodynamics is a broad subject but these terms are very significant. in each and every thermodynamic analysis the terms like path, process, cycle, properties are always used.

ReplyDeleteIs anyone else having this problem or is it a issue on my end?
I'll check back later and see if the problem still exists.
