I think in free expansion process;
du=0.
q=0.
W=0.

@Ranjit.

Please explain the example of the free expansion process.

Yes, this is right answer.

Free expansion is irreversible non flow process because there is no change in kinetic energy.

Bursting of tyre is an adiabatic process not free expansion.

Free expansion is an irreversible process in which a gas expands into an insulated evacuated chamber. It is also called Joule expansion.

Ex:

Bursting of tyre is an example of free expansion. Once a tyre burst whole air comes out and will not flow into it again.
