FAQs & Answers
- What is a physical change in science? A physical change alters the form or appearance of a substance without changing its chemical composition, such as melting, freezing, or crushing.
- How do physical changes differ from chemical changes? Physical changes do not create new substances and are usually reversible, while chemical changes result in new substances and are often irreversible.
- Can dissolving sugar in water be considered a physical change? Yes, dissolving sugar in water is a physical change because the sugar molecules remain chemically unchanged and can be recovered by evaporation.
