State two properties of 4th state of matter?

Explanation

**Step-by-Step Text Solution:**

1. **Identify the Fourth State of Matter:**
The fourth state of matter is known as plasma. Plasma is distinct from the three classical states of matter: solid, liquid, and gas.

2. **Formation of Plasma:**
Plasma can be created by heating a gas to very high temperatures or by applying a strong electromagnetic field. This process causes the gas to ionize, resulting in the formation of charged particles.

3. **Properties of Plasma:**
- **Ionized Particles:** Plasma consists of ionized particles, which include positive ions and free electrons. This ionization gives plasma its unique characteristics.
- **Conductivity:** Plasma is an excellent conductor of electricity due to the presence of charged particles. It can also respond to electromagnetic fields, which is why it is often found in stars and other celestial bodies.

4. **Examples of Plasma:**
Plasma is found in stars, including our Sun, where the high temperatures cause gases like helium to ionize, resulting in the glow that we observe.
