How to fill out physical and chemical change

How to fill out physical and chemical change

1. To fill out physical and chemical change, follow these steps:
2. Understand the difference between physical and chemical changes. Physical changes are changes in the physical properties of a substance, such as its shape, size, or state of matter, without any change in its chemical composition. Chemical changes, on the other hand, involve a chemical reaction that results in the formation of new substances with different chemical properties.
3. Identify the substance or substances involved in the change. This could be a single substance or a combination of substances.
4. Observe any visible changes that occur. For physical changes, these may include changes in shape, size, or state of matter (e.g., solid to liquid). For chemical changes, there may be changes in color, production of a gas or odor, formation of a solid precipitate, or release/absorption of energy (e.g., heat or light).
5. Describe the changes in detail, taking note of any physical or chemical properties that are altered. For physical changes, describe the changes in physical properties. For chemical changes, describe the reactants and products involved, as well as any observable changes in their physical or chemical properties.
6. Classify the change as either a physical or chemical change based on the observations made. If the change only affects the physical properties of the substance, it is a physical change. If there is evidence of a chemical reaction and the formation of new substances, it is a chemical change.
7. Summarize the changes and their classifications in a clear and concise manner.
8. Proofread and revise your description if necessary to ensure accuracy and clarity.
