Question

which of the following physical properties indicates the shininess of a substance? answer options: select one of four hardness color luster mass

Explanation:

To determine which physical property indicates the shininess of a substance, we analyze each option:

• Hardness refers to a substance's resistance to scratching or indentation, not shininess.
• Color is about the hue of a substance, not its shininess.
• Luster is defined as the way a substance reflects light, which is essentially its shininess (e.g., metals have a metallic luster, meaning they are shiny).
• Mass is a measure of the amount of matter in a substance, unrelated to shininess.

Answer:

Luster
