A cork floats in water while the iron nail sinks because the density of cork is less than that of water. Thus, the upthrust of water on the cork is greater than the weight of iron nail.

Explanation:
The reason why the cork floats while the nail sinks in water is due to the difference in their densities. Density is the measure of how much mass is contained in a given volume. When an object is placed in a fluid, such as water, it experiences an upward force called buoyancy. The buoyant force is equal to the weight of the fluid displaced by the object.
Density of Cork:
Cork is a lightweight material that is composed of cells filled with air. These air-filled cells contribute to the low density of cork. The density of cork is less than the density of water, which means that cork is less dense than water and will float on its surface.
Density of Water:
The density of water is approximately 1 gram per cubic centimeter (g/cm³) at standard conditions. This means that for an object to float in water, it must have a density less than 1 g/cm³.
Buoyant Force:
When an object is placed in water, it displaces a volume of water equal to its own volume. The weight of the water displaced by the object is equal to the buoyant force acting on the object. If the weight of the object is less than the buoyant force, the object will float. If the weight of the object is greater than the buoyant force, the object will sink.
Nail:
A nail is typically made of iron or steel, which are denser than water. The density of iron is greater than the density of water, so a nail will sink when placed in water. The weight of the nail is greater than the buoyant force exerted by the water, causing it to sink.
Cork:
Cork, on the other hand, has a lower density than water. When a cork is placed in water, it displaces a volume of water equal to its own volume. The weight of the water displaced is greater than the weight of the cork itself, resulting in a net upward buoyant force. This buoyant force is greater than the weight of the cork, causing it to float.
Conclusion:
In conclusion, the reason why the cork floats while the nail sinks in water is due to the difference in their densities. The density of cork is less than the density of water, allowing it to float, while the density of nail (made of iron) is greater than the density of water, causing it to sink.
