Which of the following is correct?

gas atoms subjected to electricity emit bright lines of light.

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 emit bright lines of light.

Explanation:  When Gas atoms are subjected to electricity, they will shake the electrons present in the atoms which would be in random motion in the atom itself.

Thus it will eject one one electron which will move into another higher energy levels releasing photons.

Thus they will emit bright lines of light.

Gas atoms do absorb white light but they donot emit a continuous spectrum of light.

what are the choices?

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
