Your task is to determine the energy cost to reset the 10-bit register to its initial state, where every particle is again in the "0" side of its cell. This can be done by using a piston to push the particles (~compressing the gas) so that they can only occupy the left side of the cell.

**1. What is the change in (dimensionless) entropy in this process?**

For this question, i figured that N=10 and final Volume should be half of Initial Volume) because it says it has to occupy only the left side of the cell which is half

and hence the change in entropy would be

__10*ln(1/2)..__

__Am i doing correctly?__

**2. What energy is required to carry out the process?**

I am totally stuck with this question.

__I am guessing that the energy required would be neglect-ably small...?__

Could someone help me out with these two questions ?

Thanks !
