Question

select the correct answer. the photograph shows matter changing states. which statement best describes what happens to the particles of matter during this change? a. tightly - packed particles gain energy, allowing them to move more freely. b. particles move more slowly and bump into one another less frequently. c. particles pack closely together, giving the matter a definite shape and volume. d. a loss of energy strengthens the attraction between particles.

Explanation:

The photograph shows an ice - cube melting, which is a change from solid to liquid state. In a solid, particles are tightly - packed. When melting occurs, the particles gain energy and start to move more freely. Option B describes a decrease in energy, option C describes a solid state characteristic, and option D describes a process opposite to melting.

Answer:

A. Tightly - packed particles gain energy, allowing them to move more freely
