Iron doesn't float. To float it has to be lighter than water. It is heavier.
The iron nail sinks in water because its density is greater than that of water. The katori floats because its shape and material make it less dense than water, allowing it to displace enough water to generate a buoyant force greater than its weight.
jk its because the boats are full of air, which is less dense than water, and so is unable to sink. if there is a hole in the boat, the air will proceed to be replaced with water, and therefore sink. There must be enough air in the boat to be able to carry the large weight of the iron.
The cork piece floats because it is less dense than water, allowing it to displace enough water to support its weight. The iron nail sinks because it is denser than water and does not displace enough water to counteract its weight, causing it to sink.
A wooden boat floats in water due to its buoyancy and the displacement of water created by the boat's weight.
An iron ball floats on mercury because mercury is much denser than iron. The buoyant force acting on the iron ball due to the displacement of mercury is greater than the gravitational force pulling it downward, causing it to float.
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
The iron nail sinks in water because its density is greater than that of water. The katori floats because its shape and material make it less dense than water, allowing it to displace enough water to generate a buoyant force greater than its weight.
Wood floats on water, but iron sinks into it.
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
Wood floats on water because it is less dense than water. When an object is less dense than the fluid it is placed in, it will float. The air pockets within the wood contribute to its buoyancy, keeping it afloat on the water's surface.
Anything which floats on water can only do so if it displaces, or moves out of the way, its own mass of water. Wood floats because it displaces a small amount of water, a large lump of iron is very heavy so it will keep displacing water until it has displaced its own mass.
the iron bob floats in Mercury because it density is less than mercurys density
Anything that doesn't float in water is less dense than water, say iron? So if you drop an iron bar into a glass of water, you can say that the iron sinks or you can interpret it as the water floats? If you are referring to liquid, then mercury.
Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
It means that mercury is denser than iron.
It is less dense than water, therefore it floats on water.
