select the correct answer.\nthe photograph shows matter changing states. which statement best describes what happens to the particles of matter during this change?\na. tightly - packed particles gain energy, allowing them to move more freely.\nb. particles move more slowly and bump into one another less frequently.\nc. particles pack closely together, giving the matter a definite shape and volume.\nd. a loss of energy strengthens the attraction between particles.
Answer
Brief Explanations:
The photograph shows ice (solid - state) melting into water (liquid - state). In a solid, particles are tightly - packed. When a solid melts, it gains heat energy. This energy allows the particles to move more freely, transitioning from a rigid, tightly - packed arrangement to a more fluid arrangement. Option A correctly describes this process. Option B is incorrect as particles gain energy and move faster during melting. Option C describes the characteristics of a solid, not the melting process. Option D is incorrect because melting is associated with a gain of energy, not a loss.
Answer:
A. Tightly - packed particles gain energy, allowing them to move more freely.
