Question
- A. Particles gain energy and move closer together
- B. Particles lose energy and move apart
- C. Particles gain energy and move apart
- D. Particles lose energy and vibrate in place
Answer
Particles gain energy and move apart
Explanation
During melting, particles gain energy, which allows them to overcome some of the forces holding them together, resulting in them moving apart and transitioning from solid to liquid.
Common mistake
The three states of matter correction for Misunderstanding Particle Ar
Students often think that particles in solids, liquids, and gases are arranged in the same way This error matters in The three states of matter because it drifts away from the objective: Use the simple particle model to represent solids, liquids and gases.
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 use the simple particle model to represent solids, liquids and gases.
