Answers
GPT 3.5
Physical changes and chemical changes are distinguished by the type of transformation that occurs in a substance.
Physical changes are changes that do not alter the chemical composition of a substance. They only affect its physical properties such as shape, size, density, state (solid, liquid, gas), and phase transitions (melting, freezing, boiling, condensation). Examples of physical changes include melting ice, boiling water, dissolving sugar in water, breaking a glass, or cutting a piece of paper.
Chemical changes, on the other hand, involve a rearrangement of atoms or molecules in a substance, resulting in the formation of new substances with different chemical properties. Chemical changes are also known as chemical reactions. Examples of chemical changes include burning wood, rusting iron, baking a cake, digesting food, or fermentation in the production of alcohol.
In summary, physical changes only affect the physical properties of a substance, while chemical changes involve a transformation of the substance at the molecular level, resulting in the formation of new substances.
