A gas does 4.5 J of external work during adiabatic expansion. If its temperature falls by 2 K, then its internal energy will be

An ideal gas at initial temperature T_(9) and initial volume V _(0) is expanded adiabatically to a volume 2V_(0). The gas is then ecp[anded isothermally to a volume 5V_(0) and there after compressed adiabatically so that the temperature of tha gas becomes again T_(0). If the final volume of the gas is alphaV_(0) then the value of constant alpha is
