Can two states of an ideal gas be connected by an isothermal process as well as an adiabatic process?
An isothermal process is represented by
PV = constant … (i),
where P = pressure, V = volume.
P1 V1 = P2 V2 (ii),
P1, V1 = initial values of pressure and volume
P2, V2 = final values of pressure and volume.
An adiabatic process is represented by
