(a) The wavelength of a Balmer series line (from n 1) or by found to be 656.5 nm. What percentage difference is found between this
and the wavelength predicted byž = R ()
[R = 1.097 x 107m]

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j ?

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

If y gets smaller as x gets bigger and y have an relationship?
