why iron nail sinks and cork float on water?

Jayanth answered this

because iron weight is more than the weight of water and cork is less than the weight of water.

Kanak D Purohit answered this

this happens due to the difference in their density related to water as iron has more density than iron so it sinks and cork has less density than water so it floats hope u get it

Ammaarah Farheen answered this

The density of a cork is less than that of water, whereas the density of a nail is greater than that of water. A substance whose density is less than that of a liquid will float on the surface of that liquid. Thus, a cork floats in water. On the other hand, a substance whose density is greater than that of a liquid will sink in that liquid. Thus, a nail sinks in water.

The nail sinks in water because the gravitational force attracts it downward toward the earth, there is an upthrust of water on the nail which pushes it upwards but, the downward force acting on the nail is greater that the upward force. Hence, the nail sinks in water. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks. The cork floats while nail sinks this happens because of the difference in their densities. The density of a substance is defined as the mass per unit volume. The density of the cork is less than the density of water. This mean the upthrust of the cork is greater than the weight of the cork. The density of the iron nail is more than that of the water, this means that the upthrust of water on the iron nail is less than the weight of the nail, so it sinks.

The density of cork is less than the density of water,it floats.The density of iron is more than the density of water,the iron sinks.

Ishaan Nair answered this

the density of the cork is lesser than water which causes it to float but when we see the case of iron,the density of iron is way much more that water therefore it will sink the moment u put it in water

Manojkumar answered this

Here the weight of the cork is less than the weight of the water.so the the cork float in water.but in iron nail it has some weight than the water

Mamta Bansal answered this

hope this ans. is correct

Taliya answered this

The density of Cork is less than water and that of iron is more than water.Then according to the principles of floatation Cork will float and iron will sink because the objects with less density than water floats and the objects with more density than water sinks.

Density high

Mahi Sudharsan answered this

The relative densities f cork and the iron nail differ.
The iron nail has more volume and density whereas, the cork has hollow spaces and hence, has less density.
Therefore, iron nail sinks and the cork floats on water.

Rashmi answered this

In case of iron bouyant force is less than the weight of iron nail
And in the case of cork bouyant is more than the weight of cork that'.s why iron sink and cork float

Garv answered this

A cork floats in water while the iron nail sinks because the density of cork is less than that of water. ... On the other hand, the density of iron nail is more than water, and the upthrust of water on iron nail is less than that of the weight of the iron nail. Thus, it sinks.

Nishant Sinha answered this

Because iron nail's density is more than the density of water therefore it sinks in water and cork has less density than water and therefore it floats in water.
