Three examples of physical changes include melting ice into water, demonstrating a phase change from solid to liquid; breaking a glass, which changes its shape but not its chemical composition; and dissolving sugar in water, where sugar particles disperse throughout the water but remain chemically unchanged. These examples highlight that physical changes affect the state or form of a material without altering its chemical identity.
FAQs & Answers
- What is a physical change? A physical change is a change in the form or state of a substance without altering its chemical composition.
- How can I tell if a change is physical or chemical? Physical changes affect only the appearance or state of a substance, like melting or breaking, while chemical changes result in the formation of new substances.
- Can dissolving be a physical change? Yes, dissolving, such as sugar in water, is a physical change because the substance disperses but remains chemically the same.
