The glow stick of a fluorescent light bulb or neon sign is caused by which state of matter?

solid
liquid
gas
plasma

Option (d) is the correct answer.

Explanation:

Plasma is defined as the ionized hot gas that contains similar number of positively charged particles and negatively charged electrons.

Since plasma is a hot gas, so it's particles have very high kinetic energy due to which they tend to move very rapidly from one place to another.

For example, neon signs and lighting have plasma.

Therefore, we can conclude that out of the given options the glow stick of a fluorescent light bulb or neon sign is caused by plasma state of matter.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
