Answer 2

The state of matter called plasma makes a fluorescent tube (or neon sign bulb) glow.

• There are four states of matter, solids, liquids, gases, and plasma.
• Plasma is the fourth state of matter.
• Plasma is an ionized gas consisting of equal numbers of positive and negatively charged particles  
• Thermodynamics cannot consider plasma as a state of matter like other states because it does not obey the physical laws that are obeyed by the other three states.

• Examples of this state are lightening the gases in a neon sign, tails of comets, etc.
