Question

1. which physical property refers to \scratchability\? a. breakage b. luster c. hardness d. streak

Explanation:

To determine the physical property related to "scratchability", we analyze each option:

• Option A (Breakage) refers to how a material breaks, not scratchability.
• Option B (Luster) describes how light reflects off a material, unrelated to scratchability.
• Option C (Hardness) measures a material's resistance to scratching or indentation, so it relates to scratchability.
• Option D (Streak) is the color of a mineral's powder, not about scratchability.

Answer:

C. Hardness
