The emitted photons have an energy equal to the difference in energy between the two states.
Q= calories
m = mass
c = specific heat
∆t = temperature difference
Also, Qin = Qout
(as in the amount of energy lost by the iron equals the energy gained by water. the water) so the calories lost is as stated in pict.
