JEE Main & Advanced Physics Thermodynamical Processes Question Bank Topic Test - Thermodynamical Process (2021)

  • question_answer
    One mole of an ideal gas expands at a constant temperature of 300 K from an initial volume of 10 litres to a final volume of 20 litres. The work done in expanding the gas is (R = 8.31 J/mole-K)

    A)       750 joules

    B) 1728 joules

    C) 1500 joules

    D) 3456 joules

    Correct Answer: B

    Solution :

    [b] \[{{W}_{iso}}=\mu RT{{\log }_{e}}\frac{{{V}_{2}}}{{{V}_{1}}}=1\times 8.31\times 300{{\log }_{e}}\frac{20}{10}=1728J\]
