What is the binding energy (in ev) associated with the n=2 orbital of hydrogen if the binding energy of the n=1 orbital is -13.6 ev?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
