Question

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

Explanation:

• A chemical change results in a new substance being formed. So, "The substance changes to a new substance" is a chemical change (C).
• If the original substance can be recovered, it indicates a physical change as no new chemical species is formed. So, "The original substance can be recovered" is a physical change (P).
• A color - change can be either a physical or chemical change. But generally, if it is due to a chemical reaction forming a new substance, it is a chemical change. So, "The color changes" is a chemical change (C).
• Production of gas is a sign of a chemical reaction taking place, so "Gas is produced and given off" is a chemical change (C).
• Changes in size, shape, or volume are physical changes as they do not involve the formation of a new substance. So, "The substance changes size, shape, or volume" is a physical change (P).

Answer:

• The substance changes to a new substance: C
• The original substance can be recovered: P
• The color changes: C
• Gas is produced and given off: C
• The substance changes size, shape, or volume: P
