Question

What action describes a chemical change?

freezing water, melting ice, lighting a match, or crushing rock.​

Answer 1

Lighting a match

Step-by-step explanation:

Lighting a match and letting is burn is an example of a chemical change because the two reactants (fire and the match) form a new substance. Freezing water, melting ice and crushing a rock are physical changes because they only change in size, shape or form.

Answer 2

Lighting a match.

Step-by-step explanation:

When the match burns it goes through a chemical change due to the materials such as phosphate, sulfur, etc. The heat then burns the phosphorous on the match's head.
