FAQs & Answers
- What is a physical change? A physical change is a process that alters the form or appearance of a material without changing its chemical composition, such as melting, freezing, or cutting.
- How can you tell if a change is physical or chemical? A physical change affects only the state or appearance and is usually reversible, while a chemical change results in a new substance and is 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 disperse but do not change chemically.
- Why is melting ice considered a physical change? Melting ice changes water from a solid to a liquid state without altering the chemical composition of H2O, making it a physical change.
