Point Function;_( बिंदु फलन )

           A Point function (also known as state function) is a function whose value depends on the final and initial states of the thermodynamic process, irrespective of the path followed by the process.

Example of point functions are density, enthalpy, internal energy, entropy etc.

Difference between point function and path function ;- 8)

Sr. no.	Point Function	Path Function
1	Its values are based on the state of the system (i.e. pressure, volume, temperature etc.)	Its values are based on how that particular thermodynamic state is achieved.
2	No matter by which process the state is obtained, its values will always remain the same.	Different processes to obtain a particular state will give us different values.
3	Only initial and final states of the process are sufficient	We need to know exact path followed by the process
4	Its values are independent of the path followed	Its values are dependent on the path followed
5	It is an exact or perfect differential	It is an inexact or imperfect differential.
6	Its cyclic integral is always zero	Its cyclic integral may or may not be zero
7	It is property of the system	It is not the property of the system
8	Its examples are density, enthalpy, internal energy, entropy etc	Its examples are Heat, work etc.

THERMODYNAMIC PROPERTIES ,PROCESSES & CYCLES

             Every system has certain characteristics by which its physics condition may be describe, e.g volume, temperature, pressure, etc. Such characteristics are called properties of the system.  These are all microscopy in nature. When all the properties of a system have definite Values, the system is said to exist at a definite state. Properties are the coordinates to describe the state of a system. They are the state variable of the system. Any operation in which one or more of the properties of a system change is called a change of state. The succession of states passed through during a change of state is called the path of the change of state. When the path is completely specified, the change of state is called a processes, e.g. a constant pressure process. 

             A thermodynamic cycle is defined as a series of state change such that the final state is identical which the initial state. 

A process and a cycle process 

                Properties may be of two types. Intensive properties are independent of the mass in the system, e.g. pressure, temperature, etc. Extensive properties also increase. Specific extensive properties, i.e. extensive properties per unit mass, are intensive properties, e.g. specific volume, specific energy, etc.
