Which term describes an object that is moved vertically to pound or pulverize a material?

• A. Irregular
• B. Malleability
• C. Pestle
• D. Platinum

Answer: (C)

This item tests knowing the name of the tool used to crush materials by pounding them. The term describes the handheld piece you move up and down to pulverize substances inside a mortar. The pestle is designed for vertical pounding and grinding, shaping the material by applying force in a downward motion against the mortar’s surface. The other options don’t fit: “irregular” describes shape, not a tool; “malleability” is a property of a material’s ability to be hammered or shaped, not the instrument; and “platinum” is a metal, not something used to pound substances. So the correct term is pestle.
