The correct Answer is:
To answer the question, "The solid like conducting state of gases with free electrons is called," we need to identify the correct term that describes this state of matter. ### Step-by-Step Solution: 1. **Understanding Matter**: Matter is anything that occupies space and has mass. It can exist in different states, primarily solid, liquid, and gas. 2. **States of Matter**: Besides the common states (solid, liquid, gas), there are other states such as plasma. Plasma is often referred to as the fourth state of matter. 3. **Characteristics of Plasma**: Plasma consists of ionized gases, which means it contains free electrons and ions. This state occurs when sufficient energy is provided to a gas, causing the atoms to lose some of their electrons. 4. **Solid-like Conducting State**: The question specifically mentions a "solid-like conducting state of gases with free electrons." This description aligns with plasma, as it exhibits properties similar to solids in terms of conductivity due to the presence of free-moving charged particles (electrons). 5. **Conclusion**: Therefore, the solid-like conducting state of gases with free electrons is called **plasma**. ### Final Answer: The solid-like conducting state of gases with free electrons is called **plasma**.

Assertion : The resistivity of a semiconductor increases with temperature. Reason: In a conducting solid, the rate of collisions between free electrons and ions increases with increase of temperature.

Using the microscopic form of Ohm's law (J=sigma E) , prove that conductivity of a metal can be written as sigma="ne"mu . Here n is the number of free electrons per unit volume and mu is mobility of free electrons . In case of semiconductors there are two types of conduction particles, one is free electrons and the other is known as a hole. Charge on the hole may be assumed to be equal and opposite of that on electron. The number density of free electrons and holes in the semiconducting material are n and p respectively.

The elctrostatic forces of attraction between the metallic ions and free electrons is called ______.

A. The energy band of valence electrons is called Valence band B. The energy band of free electrons or loosely bound electrons is called conduction band.

During sublimation the solid substance which is converting to geseous state is called _________.

Assertion: If there is some gap between the conduction band and the valence band, electrons in the valence band all remain bound and no free electrons are available in the conduction band. Then the material is an insulator. Reason: Resistance of insulators is very low
