Physical vs Chemical Properties Classification with Checked Results

Label each description by asking whether the substance changes form only or turns into a new substance. This simple rule separates observable traits like color, mass, or melting point from reaction-based behavior such as rusting, burning, or gas release.

The verified list below assigns each statement to the correct group using standard science criteria. Changes that keep the same substance intact belong to one group, while changes that create a different substance belong to the other. Examples include solubility in water versus oxidation in air.

Review errors carefully. If a statement mentions heat, light, bubbles, or residue formation, reclassify it as reaction-based behavior. If it focuses on measurement or appearance without substance change, place it with observable traits.
