    Answer:

    The final energy is 1,700 J

    Explanation: According to first law of thermodynamics:

    =Final energy-initial energy=Change in internal energy

    q = heat absorbed or released

    w = work done by or on the system

    w = work done by the system=  {Work done by the system is negative as the final volume is greater than initial volume}

    q = +500J   {Heat absorbed by the system is positive}

    w = work done by the system = -300J
