Which statement is true? which statement is true? gas atoms subjected to electricity emit bright lines. gas atoms absorb white light and emit a continuous spectrum of light. gas atoms under high pressure emit dark lines against a continuous spectrum. gas atoms heated to a high temperature emit white light. gas atoms subjected to electricity do not emit a spectrum.

Gas atoms subjected to electricity emit bright lines.

Explanation:

Gas atoms subject to electricity emit bright lines. This can be seen in fluorescent lamps, for example.

Fluorescent lamps work by ionizing atoms of argon gas and mercury vapor. After receiving an electric current, ionization occurs, at that moment the atoms are accelerated by the potential difference established between the lamp terminals and emit bright light and electromagnetic waves when they return to the natural state.
