Be sure to answer all parts. A sample of nitrogen gas expands in volume from 1.4 to 5.8 L at constant temperature. Calculate the work done in joules if the gas expands (a) against a vacuum: J (b) against a constant pressure of 0.73 atm: * 10 J Enter your answer in scientific notation. (c) against a constant pressure of 4.1 atm: * 10 J Enter your answer in scientific notation.

    Answer: 0, 3.212J, 18.04J

    Explanation:

    a) Work done by gae against vacuum is zero because in vacuum Pressure = 0

    W=P️V

    =0 x (5.8-1.4)

    = 0 Ans

    b)

    W=P️V

    = 0.73 x (5.8-1.4)

    = 3.212 J

    c)

    W = P️V

    =4.1 x (5.8-1.4)

    = 18.04 J
