Question Analysis
This question evaluates the student's understanding of the characteristics of a gas, including particle arrangement, interparticle forces, and particle motion.

Key Concept Explanation
In a gas, the particles are highly dispersed and move randomly due to the high kinetic energy they possess. The interparticle forces in a gas are very weak, which allows the particles to move freely and rapidly in all directions. Gases do not have a fixed shape or volume, as the particles can spread out to fill any container.

Step-by-step Solution
1. Describe the particle arrangement in a gas as highly dispersed and random.
2. Explain that the interparticle forces in a gas are very weak.
3. State that gases do not have a fixed shape or volume.
4. Explain that the particle...
