A gas with inital volume of 0.02m° expands.in a piston -cylinder assembly from 8 bar to 2bar in a process dunng wich the relationbetween pressure and volume is pt" = constantwith n= 1.2, The mass of the gas is o-25 kg. ifthe Speafic internal energy of the gas decreasesby 55 KJ/ kg duning the process, determine theheat transfer by neglecting kinetic and potentialenergy effects. Present answer in kJ.
