Changes that are irreversible typically involve permanent alterations to the fundamental structure or composition of a substance or system. Examples include chemical reactions, such as combustion or rusting, where the original materials cannot be recovered. Additionally, certain physical changes, like the destruction of a habitat or the extinction of a species, also represent irreversible changes. Once these transformations occur, restoring the original state is either impossible or highly impractical.

What is the three key phrases that describe reversible changes?
Reversible changes can be described by the phrases: "no permanent alteration," "easily undone," and "physical state alteration." These changes involve modifications that can be reversed without affecting the material's chemical composition, such as melting ice or dissolving sugar in water.
