### In the lessons

In science lessons "chemically" helps describe chemical changes: when wood burns or iron rusts, it changes chemically into new substances, unlike melting ice, which is a physical change. In everyday life it appears on labels: chemically treated, chemically cleaned. Phrases: chemically identical, chemically different, react chemically.

### Examples

### Note

Adverb of "chemical" (+ly → chemically, with -ally). Pronounced KEM-ik-lee; the "ch" sounds like k. Key science idea: a chemical change makes a new substance; a physical change does not.
