**Step-by-Step Solution:** 1. **Understanding Gas Behavior**: Gases consist of molecules that are in constant motion. Unlike solids and liquids, gas molecules are not closely packed together. 2. **Molecular Distance**: In a gas, the molecules are far apart from each other. This large distance between gas molecules means that they have a lot of space to move around freely. 3. **Negligible Forces of Attraction**: The forces of attraction between gas molecules are very weak compared to those in liquids and solids. This negligible force allows gas molecules to move independently of one another. ...
