  1. Question 1

    Q1. The change in internal energy of a system is zero when the process is

    • A) Isothermal
    • B) Adiabatic
    • C) Isobaric
    • D) Isochoric

    Answer: Isothermal

    Explanation: For an ideal gas, internal energy (U) depends only on temperature. In an isothermal process, temperature remains constant, so ΔU = 0.
