Explain how a colored light is produced from an atom.

When the atoms of a gas or vapor are excited, for instance by heating or by applying an electrical field, their electrons are able to move from their ground state to higher energy levels. This energy corresponds to particular wavelengths of light, and so produces particular colors of light.

Explanation:

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

the temperature of the gas, in k, not celsius.
