FAQs & Answers
- What is the difference between a physical and a chemical change? A physical change affects the form or state of a substance without changing its chemical composition, while a chemical change results in the formation of one or more new substances with different properties.
- Can you give examples of physical changes? Yes, examples of physical changes include freezing water into ice, crushing a can, chopping wood, dissolving sugar in water, and melting wax.
- What are some common examples of chemical changes? Common chemical changes include rusting of iron, burning wood, digesting food, baking a cake, and fermenting grapes into wine.
- How can you tell if a change is physical or chemical? You can tell by observing if the change alters the substance's chemical composition (chemical change) or just its physical appearance/state (physical change). Chemical changes often involve color change, gas production, or temperature change.
