As the energy difference between the ground and excited state decreases, the excited-state population decreases. This is because there is less energy available to excite the atoms to the higher energy state. As the temperature of the flame increases, the excited-state population increases. This is because higher temperatures increase the kinetic energy of the atoms, making it more likely for them to reach the excited state.
