Assume hydrogen atoms in a gas are initially in their ground state. if free electrons with kinetic energy 12.75 ev collide with these atoms, what photon wavelengths will be emitted by the gas?

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
