Calculate the wavelength and frequency of an electron when there is a quantum jump from n=1 Assume
E=-13.6eV/n
1eV = 1.6 x10-19
1.6 x10-19 n is the quantum number] )

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

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change? work power gravitational energy chemical energy
