Thermodynamic Processes

[caesiumrabbit]

Thermodynamic processes in systems can be named as following:

 

1.Pressure remains constant-Isobaric process

2.Volume remains constant-Isochoric process

3.Temperature remains constant-Isothermal process

4.Thermally insulated-Adiabatic process

5.*************-Polytropic process

 

 

Q1)In a piston-cylinder device, all P,V,T properties can change. What is the name for a such process?

 

Q2)What is the physical condition for Polytropic process?

 

Q3)For adiabatic process, mathematically we say that PV^r=constant

Here r(gamma)=specific heat ratio

 

For Polytropic process it is PV^n=constant

Is this n can be any real number?
