What will an object do if its density is less than the density of water?

• A. It will remain suspended in the middle of the water.
• B. It will float on water.
• C. It will dissolve in water.
• D. It will sink to the bottom of the water.

Answer: (B)

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 when an object is placed in a fluid (like water), its behavior depends on the comparison between the object's density and the fluid's density.
3. If the object's density is less than the density of water, it means the object is lighter per unit volume compared to water.
4. According to the principle of buoyancy, an object less dense than the fluid will experience an upward buoyant force greater than its weight, causing it to float.
5. Therefore, an object with density less than water will float on the surface rather than sinking or remaining suspended.
