Answer

Brief Explanations:

Un cambio físico es aquel en el que la sustancia mantiene su identidad química, solo cambia su estado físico o apariencia. La formación y fusión del hielo son cambios físicos porque el agua simplemente cambia de estado sólido a líquido y viceversa, sin que su composición química cambie. La combustion del papel, la formación de óxido de hierro (rust) y la reacción entre vinagre y bicarbonato son cambios químicos donde se forman nuevas sustancias.

Answer:

ice forming and then melting back into water
