Question Analysis
This question evaluates the student's understanding of the particle arrangement and motion in different states of matter, specifically focusing on the characteristics of a gas.

Key Concept Explanation
In a gas, particles are highly dispersed and move randomly with high kinetic energy. The interparticle forces are weak, allowing the particles to spread out and fill the entire container.

Step-by-step Solution
1. Identify the key characteristics of a gas: highly dispersed, random, and fast-moving particles.
2. Compare the given options to these characteristics:
Option A: Tightly packed, ordered, and slow-moving (describes a solid).
Option B: Loosely packed, disordered, and fast-moving (describes a gas).
Opt...
