when matter undergoes a physical change, some of its physical properties may change but its identity does not. when matter undergoes a chemical change, its identity changes and so the matters original properties are replaced by new properties. use the drop - down menus to label each of the following changes p for physical change and c for chemical change. the substance changes to a new substance. the original substance can be recovered. the color changes. gas is produced and given off. the substance changes size, shape, or volume. done
Answer
Brief Explanations:
- A chemical change results in a new substance, so "The substance changes to a new substance." is a chemical change (C).
- In a physical change, the original substance can be recovered, so "The original substance can be recovered." is a physical change (P).
- A color - change can be due to both physical and chemical changes, but more often it is a chemical change, so "The color changes." is a chemical change (C).
- Gas production is a sign of a chemical reaction, so "Gas is produced and given off." is a chemical change (C).
- Changes in size, shape, or volume are physical changes as the identity of the substance remains the same, so "The substance changes size, shape, or volume." is a physical change (P).
Answer:
- C. The substance changes to a new substance.
- P. The original substance can be recovered.
- C. The color changes.
- C. Gas is produced and given off.
