question: Heating ice to its melting point (0°c) gives its molecules enough energy to do what?
distractor3: freeze
distractor1: settle
distractor2: evaporate
correct_answer: move
support: Adding energy to matter gives its atoms or molecules the ability to resist some of the forces holding them together. For example, heating ice to its melting point (0°C) gives its molecules enough energy to move. The ice melts and becomes liquid water. Similarly, heating liquid water to its boiling point (100°C) gives its molecules enough energy to pull apart from one another so they no longer have contact. The liquid water vaporizes and becomes water vapor.
