How bonding and structure are related to the properties of substances
Question
- A. Particles gain energy and move closer together
- B. Particles lose energy and move further apart
- C. Particles gain energy and move further apart
- D. Particles lose energy and vibrate less
Answer
Particles gain energy and move further apart
Explanation
During melting, particles gain energy, which allows them to overcome some of the forces holding them together, leading to a change from solid to liquid.
Common mistake
The three states of matter correction for Confusing Particle Types.
Students often confuse the types of particles present in different substances, such as treating ionic compounds as if they are made of molecules instead of ions This error matters in The three states of matter because it drifts away from the objective: Link the type of particles present to the bonding and structure of the substance.
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 link the type of particles present to the bonding and structure of the substance.
