# How does the distribution curve gets modified if I take some molecules out of the gaseous system following the Maxwell-Boltzmann law?

If you have a gas of molecules following Maxwell-Boltzmann distribution then plot for the distribution curve is gaussian. Now, If I take out some molecules from it then how does the distribution curve gets modified?

• How are you taking them out? Are you using effusion?

If the Maxwellian is normalized to the number of molecules $$N$$, after extracting $$n$$ molecules and after equilibration, you'll get a Maxwellian normalized to $$N-n$$.
