What will happen to an object if its density is greater than that of the surrounding liquid?

• A. The object will float on the surface of the liquid.
• B. The object will dissolve in the liquid.
• C. The object will remain suspended in the middle of the liquid.
• D. The object will sink in the liquid.

Answer: (D)

Verified step by step guidance

1. Recall the concept of density, which is defined as mass per unit volume, mathematically expressed as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
2. Understand that whether an object sinks or floats in a liquid depends on the relative densities of the object and the liquid.
3. If the object's density is greater than the density of the surrounding liquid, the object is heavier per unit volume compared to the liquid.
4. According to the principle of buoyancy, an object will sink if its density is greater than that of the liquid because the buoyant force is not enough to support its weight.
5. Therefore, the object will sink in the liquid when its density is greater than that of the surrounding liquid.
