Question

which of the following is an example of a physical change? metal rusting after being left out in the rain honey dissolving in tea sugar and oxygen reacting to produce water and carbon dioxide a raw egg being cooked

Explanation:

A physical change is a change in which no new substances are formed. When honey dissolves in tea, it is just a change in the state of the honey (from solid - like in its jar form to dissolved in the liquid tea) and no new chemical substances are created. Rusting of metal is a chemical change as iron reacts with oxygen and water to form iron oxides (new substances). The reaction of sugar and oxygen to produce water and carbon dioxide is a chemical reaction (combustion or respiration - like process). Cooking a raw egg causes denaturation of proteins (a chemical change as the protein structure is altered and new properties are exhibited).

Answer:

honey dissolving in tea
