<span>The light spectrum that results from the light produced by an excited electron moving from a higher energy level back down to a lower energy level is an emission spectrum. The emission spectrum is formed by the electromagnetic radiation released by the transition in energy state.</span>
Answer is: emission spectrum. When atom or molecule moves from a high energy level to a lower energy level than chemical element<span> or </span>chemical compound<span> emits spectrum of </span>frequencies<span> of </span>electromagnetic radiation with specific energy. That energy is <span>equal to the energy difference between the two levels.</span>
The water from the lake must first evaporate from the liquid state to the gaseous state and then condense in the air to form vapors. The water molecules absorb energy while evaporating and release it when condensing. Their motion gets faster when they are evaporating and slows back down upon condensation.
I could create a slower reaction because the particles might be moving slower due to the cold. if it was warm there will be a faster reaction. similar to the elements movements in solids and liquids.
