Answer
Physical changes- metal getting warmer, water condensing, soot depositing
chemical changes- the match burns.
Work Step by Step
During physical changes, the substance changes its physical appearance, but not its chemical composition. This includes things like physical observations (color, texture) melting and boiling points, density, and state.
Chemical changes involve a transformation of one substance into a chemically different substance. This means that changes that involve other substances will tend to be chemical changes.
This question asks us to determine whether a change is physical or chemical. The specific changes are a match burning, metal getting warmer, water condensing, soot depositing. The first change is chemical, as the final product is chemically different than the first. The next three are all physical changes. The final chemical product involved in the three is the same as the first, making it a physical change.
