Question

describe la relación de los átomos mostrados arriba. un cambio en el estado de la materia de líquido a gas es un cambio físico. la reorganización de átomos es un cambio químico un cambio en el estado de la materia de sólido a líquido es un cambio químico la estabilidad de los átomos en la molécula significa un cambio físico.

Explanation:

To solve this, we analyze each option:

• Option 1: A change from liquid to gas (like evaporation/boiling) is a physical change (no new substance, just state change), and the image likely shows a state change (atoms moving from a more ordered liquid - like bottom - to less ordered gas - like top). This matches.
• Option 2: Reorganizing atoms as a chemical change is incorrect; chemical change involves new substances, not just atom reorganization in state change.
• Option 3: Solid to liquid state change being chemical is wrong; it's physical (melting, no new substance).
• Option 4: Stability of atoms in a molecule as physical change is incorrect; molecular stability changes in chemical reactions, and this is about state change, not molecular stability.

Answer:

A. Un cambio en el estado de la materia de líquido a gas es un cambio físico.
