The temperature needed to excite the hydrogen atoms to first
excited level is:
(Boltzman constant = 1.381 × 10^-23 J/K)
Show answer and solution
According to kinetic interpretation of temperature, the average
kinetic energy per atom
[IMAGE] Energy required to excite the atoms to first excited state is
[IMAGE] 10.2 × 1.6 × 10^-19
T = 7.88 ´ 10^4 K
