Answer
Brief Explanations:
Physical properties of matter can be observed or measured without changing the substance's identity, like color or density. A chemical property describes a substance's ability to undergo a chemical change, such as flammability. A physical change doesn't alter the chemical composition, like melting ice. A chemical change results in a new substance, like rusting iron. Matter is anything that has mass and takes up space. A property is a characteristic of matter. A change is an alteration in matter. A substance is a form of matter with a definite composition and distinct properties. For the vocabulary self - evaluation, if you are familiar with a word in the context of matter's properties and changes, mark it with '+', give an example like "Density is a physical property, e.g., lead is denser than wood" and define it. If you can only do one (define or give an example), mark '/', and if it's new, mark '-'.
Answer:
| WORD | + | / | - | Example | Definition |
|---|---|---|---|---|---|
| physical | + | Melting point is a physical property. Ice melts at 0°C. | A characteristic of matter that can be observed or measured without changing the substance's chemical identity. | ||
| chemical | + | Combustion is a chemical property. Wood burns in air. | A characteristic of a substance that describes its ability to undergo a chemical reaction and form new substances. | ||
| property | + | Color is a property of matter. A red apple has the property of redness. | A characteristic or quality of a substance or object. | ||
| matter | + | A book is matter as it has mass and takes up space. | Anything that has mass and occupies space. | ||
| change | + | Tearing paper is a physical change. Burning paper is a chemical change. | An alteration in the state or condition of matter. | ||
