How bonding and structure are related to the properties of substances
Question
- A. Gases have a definite shape.
- B. Gases are composed of particles that are far apart.
- C. Gases have strong intermolecular forces.
- D. Gases do not occupy space.
Answer
The correct option is Gases have strong intermolecular forces.. This answer is correct because it matches the approved learning objective to (HT only) Explain limitations of a simple particle model that represents particles as solid inelastic spheres with no forces between them in the subtopic The three states of matter.
Explanation
The correct option is Gases have strong intermolecular forces.. Gases have strong intermolecular forces. is correct because it directly supports the approved learning objective to (HT only) Explain limitations of a simple particle model that represents particles as solid inelastic spheres with no forces between them. This belongs to the subtopic The three states of matter within How bonding and structure are related to the properties of substances, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The three states of matter.
Common mistake
The three states of matter correction for Misunderstanding Particle Mo
Students often believe that the simple particle model accurately represents all properties of solids, liquids, and gases without considering the forces between particles This error matters in The three states of matter because it drifts away from the objective: (HT only) Explain limitations of a simple particle model that represents particles as solid inelastic spheres with no forces between them.
Correct it by naming the exact chemistry idea, using precise bonding or structure vocabulary, and linking the answer back to The three states of matter. For this objective, students should (ht only) explain limitations of a simple particle model that represents particles as solid inelastic spheres with no forces between them.
