Identify an example of plasma as a state of matter.
Neon sign bulbs
The correct answer is option 4 i.e. Neon sign bulbs.
- Neon sign bulbs are an example of plasma as a state of matter. Plasma is the fourth state of matter (after solid, liquid, and gas) and is composed of ionized gases. It consists of positively charged ions and free electrons.
- In neon sign bulbs, neon gas is electrically excited, causing it to ionize and produce a glowing effect. This ionized gas is a form of plasma, which emits light due to the movement of electrons within the gas.
- Neon signs are a common example where plasma is visibly used in everyday life, creating bright, colorful displays.
