It looks like you're asking about distinguishing between physical and chemical changes. Here's a quick overview related to your notes:

  1. Physical Change: A change that alters the form or appearance of a substance but does not change its chemical composition. Examples include melting, freezing, and phase changes (like water changing from ice to liquid).

  2. Chemical Change: A change that results in the formation of new chemical substances. Indicators include change in color, temperature, gas production, or the formation of a precipitate. Burning wood is a chemical change because it transforms the wood into ash, smoke, and gases through combustion.

Based on what you provided:

  • "Only a phase change occurs": This refers to a physical change, such as ice melting to water.
  • "Burning wood": This indicates a chemical change.
