Explanation:
Matter, which constitutes every known substances is said to exists in three states namely: gaseous, solid and liquid. Each state of matter contain particles that make up their structure.
- Solids have well arranged particles that are tightly packed together to give it its solid shape. Example is wood
- Liquids have particles that are loosely packed together, hence, can still move about. Example is water
- Gases have particles that are not packed together, hence, their ability to roam freely. Example is neon gas
Based on this, the order of MOST to LEAST ordered particle arrangement is solid - liquid- gas i.e. wood - water - neon gas.
