  1. Question 1

    Q1. For an ideal gas, the work done in an isothermal expansion from V1 to V2 is given by

    • A) nRT ln(V2/V1)
    • B) nRT ln(V1/V2)
    • C) P(V2 - V1)
    • D) nR(T2 - T1)

    Answer: nRT ln(V2/V1)

    Explanation: Work done in isothermal expansion is given by nRT ln(V2/V1), derived from the ideal gas law and the definition of work.
