iii. essay writing question 1. list at least three physical properties of tap water. 2. explain why the mass of an object cannot help you identify what material the object is made from.

Explanation:

1. Physical properties of tap - water include its color (usually colorless), odor (usually odorless), and state (liquid at room temperature). These are observable characteristics without changing the substance's chemical composition.
2. Mass is a measure of the amount of matter in an object. Different materials can have the same mass depending on their quantity. For example, a small amount of a dense material like lead can have the same mass as a large amount of a less - dense material like cotton.
