Question Analysis
This question evaluates the student's understanding of the fundamental differences in particle arrangement and interparticle forces between solids and gases.

Key Concept Explanation
The state of matter is determined by the arrangement of particles and the strength of interparticle forces. Solids have a fixed shape and volume due to their ordered, tightly packed particles and strong interparticle forces. Gases, on the other hand, have no fixed shape or volume because their particles are highly dispersed and move randomly with very weak interparticle forces.

Step-by-step Solution
1. Identify the key characteristics of a solid: tightly packed, ordered lattice structure, and strong interparticle forces.
2. Identify the key characteristics of a gas: highly dispersed, random motion, and very weak interparticle forces.
3. Compare the par...
