Question

1. what moves into or out of a substance during a change of state? * 1 point thermal energy matter mass cells

Explanation:

A change of state (e.g., melting, boiling) involves a transfer of thermal energy. Adding thermal energy increases particle motion (e.g., solid to liquid), while removing it decreases motion (e.g., liquid to solid). Matter, mass, and cells do not move into/out of the substance during this process.

Answer:

Thermal energy
