The correct option for free expansion of an ideal gas under adiabatic condition is : [NEET 2020]

\( \mathrm{q}=0, \Delta \mathrm{T}<0 \) and \( \mathrm{w}>0 \)

\( \mathrm{q}<0, \Delta \mathrm{T}=0 \) and \( \mathrm{w}=0 \)

\( \mathrm{q}>0, \Delta \mathrm{T}>0 \) and \( \mathrm{w}>0 \)

\( \mathrm{q}=0, \Delta \mathrm{T}=0 \) and \( \mathrm{w}=0 \)
