how to perform a reversible isobaric process if it is possible whether practically or theoretically ?
The thermodynamic process is called reversible if it can go both forward and backwards , and if this process is initially in the forward and then backwards and the system returns to its initial state, the environment and the system remains any changes.If the process does not satisfy these conditions , it is irreversible.
For example, if we take the cylinder with the piston and the volume will be changed, the piston will be rised, andthen you can spend the same work to return the piston to its original condition. thereforeisobaric process is reversible. It is possible.
