Physics Question from JEE Main 2026 · 22 January, Shift 1

The volume of an ideal gas increases 88 times and temperature becomes (14)th\left(\frac{1}{4}\right)^{\text{th}} of initial temperature during a reversible change. If there is no exchange of heat in this process (ΔQ=0)(\Delta Q=0), then identify the gas from the following options (Assuming the gases given in the options are ideal gases):

  • A

    He

  • B

    O2\mathrm{O_2}

  • C

    CO2\mathrm{CO_2}

  • D

    NH3\mathrm{NH_3}
