A polytropic process is a process where ( P ) ( V )^n is maintained throughout the process; commonly a compression or an expansion. The n is called the polytropic exponent and is often between 1.0 and k , the specific heat ratio. For a reversible, polytropic, and nonflow process : WB = [ ( P2 ) ( V2 ) - ( P1 ) ( V1 ) ] / [ 1 - n ] or WB = [ 1 / 1 - n ][ ( P1 ) ( V1 ] [ ( P2 / P1 )^B - 1 ] B = ( n - 1 ) / ( n ) For a reversible, polytropic, and steady flow process : WSF = [ n / 1 - n ] [ ( P1 ) ( V1 )] [ ( P2 / P1 )^B - 1 ] B = ( n - 1 ) / ( n )
In Polytropic process the product of Pressure and Volume (PV) power 'n' is constant where, 'n' is polytropic index
The polytropic index in thermodynamics is a measure of how a gas behaves during a polytropic process, where pressure and volume change. It indicates the relationship between pressure and volume changes in the process. The value of the polytropic index affects the efficiency and work done in the process. A higher polytropic index means more work is done, while a lower index means less work is done.
An example problem of a polytropic process is when a gas undergoes compression or expansion while its pressure and volume change, following a specific mathematical relationship known as a polytropic equation.
Polytropic work refers to the work done in a process where the relationship between pressure and volume follows a specific power-law equation (P*V^n = constant). It is commonly encountered in compressible flow systems and is expressed as the area under the curve on a P-V diagram for a polytropic process.
the value of polytropic exponent "n" in reversible process will vary from 1 to adiabatic constant "gamma"

Thermodynamic polytropic processes are processes that can be described using the polytropic equation ( PV^n = C ), where ( P ) is pressure, ( V ) is volume, ( N ) is the polytropic exponent, and ( C ) is a constant. These processes can encompass a range of behaviors, from isobaric to isothermal to adiabatic processes, depending on the value of the polytropic exponent.

In a polytropic process, the net heat change depends on the specific conditions of the process (e.g., if it is adiabatic or not, reversible or irreversible). In general, the net heat change can be calculated by comparing the heat added or removed during the process with the work done by the system.

A reversible process is one that can be undone with no change in entropy of the system and surroundings. A cyclic process is one that starts and ends at the same state, with the system going through a series of state changes. All reversible processes are cyclic, but not all cyclic processes are reversible.
This is a reversible process.
In thermodynamics, an isentropic process is a reversible and adiabatic process, meaning there is no heat exchange with the surroundings. An adiabatic process, on the other hand, does not necessarily have to be reversible, but it also involves no heat exchange with the surroundings.
No, an isothermal process is not necessarily internally reversible.
