force.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color has-link-color has-large-font-size wp-elements-671cf1a5a17d98bb48d104a66f74b78f\" style=\"color:#000060\"><strong>Types of

restore the original state.<\/li>\n\n\n\n<li>Examples: Melting of ice into water (can freeze back to ice), stretching a rubber band (returns to its shape), or dissolving sugar in water (can be recovered by evaporation).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Irreversible Changes<\/strong>\n<ul class=\"wp-block-list\">\n<li>Changes that cannot be undone or

Concepts<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li>Phase changes (solid, liquid, gas) are reversible because they involve physical
