A sealed and thermally insulated container of total volume V is divided into two equal volumes by an impermeable wall. The left half of the container is initially occupied by n moles of an ideal(adsbygoogle = window.adsbygoogle || []).push({});

gas at temperature T. Which of the following gives the change in entropy of the system when

the wall is suddenly removed and the gas expands to fill the entire volume?

thermo is a very weak subject for me... any help is appreciated

I know that entropy is s=k*g where g is the number of accessible states, but i'm not sure where to go from here
