In the isothermal expansion of an ideal gas

A sample of ideal gas undergoes isothermal expansion in a reversible manner from volume V_(1) to volume V_(2) . The initial pressure is P_(1) and the final pressure is P_(2) . The same sample is then allowed to undergoes reversible expansion under adiabatic conditions from volume V_(1) to V_(2) . The initial pressure being same but final pressure is P_(3) . The work of expansion in adiabatic process (w_(adi)) is related to work of expansion in isothermal process (w_(iso)) is
