✅ 10 One-Sentence Answer Questions

📘 Concept-Based (5 questions)

1. Why do solids have strong particle attraction?
   → Because the particles are closely packed together.
2. What happens to the spaces between particles from solid to gas?
   → The spaces increase from solid to gas.
3. Why is the kinetic energy highest in gases?
   → Because the particles move freely with high speed.
4. What is the relationship between particle spacing and force of attraction?
   → As particle spacing increases, the force of attraction decreases.
5. Why do liquids have intermediate properties between solids and gases?
   → Because their particle spacing and attraction are between those of solids and gases.
