which of the following is a physical change? freezing water baking bread rusting metal rotting fruit
Answer
Brief Explanations:
A physical change is a change in which no new substances are formed. Freezing water is a physical change as it only changes the state of water from liquid to solid (ice). Baking bread involves chemical reactions (e.g., yeast fermentation, Maillard reaction) that create new substances. Rusting metal (e.g., iron reacting with oxygen to form iron oxide) and rotting fruit (biochemical decomposition) are also chemical changes as new substances are produced.
