Question

complete the paragraph using words from the word bank. word bank: appearance, original, changes, physical, chemical, cutting, transforms, vinegar. changes in matter can be grouped into two types: physical changes and chemical changes. physical changes involve changes in the appearance or form of a substance without it becoming a different substance. examples include cutting a piece of paper or bending a pipe cleaner. in contrast, chemical changes occur when a substance transforms into something new. mixing baking soda and vinegar to create bubbles is an example of a chemical change. other examples include rusting metal, burning wood, or baking a cake. clues to differentiate between physical and chemical changes include color changes, the production of bubbles, heat, or light. in addition, the inability to revert the substance back to its original form suggests a chemical change.

Explanation:

Matter can have physical or chemical changes. Physical changes affect appearance/form without altering the substance, like cutting paper. Chemical changes transform a substance into a new one, such as mixing baking - soda and vinegar. Clues for differentiation include color change, gas production, heat/light release, and irreversibility.

Changes; chemical; appearance; cutting; transforms; vinegar; physical; original
