WebThe polyols, ethylene glycol, glycerol, PEG 200 and also urea all show decreases in melting enthalpy, while betaine and sucrose display increases with increasing concentration of cosolvent. The large stabilizing PEG 1450 shows no change within the experimental errors. WebSep 3, 2024 · Physical: boiling and melting are physical changes. When water boils, no bonds are broken or formed. The change could be written: H 2 O ( l) → H 2 O ( g) Chemical: The dark grey nail changes color to form an orange flaky substance (the rust); this must be a chemical change. Color changes indicate chemical change.
