Cork floats because it has less density than steel
The best explanation for why steel sinks in water and cork floats is their density. Cork is light enough that it does not break the surface tension and can float.
the density of the iron nail is greater than that of the water, thus sinking
the water is more dense than the cork, thus the cork floats.
Cork is less dense than water because it floats. Both glass and Mercury (a metal) are denser than water.
Cork can absorb water.
No. It may soften the cork but if anything hot water will make the cork expand.
Cork is a light weight wood product that will float in water.
Ice cubes are denser than cork. To test this yourself, take an identical size cube of each one, and weigh each on accurate scales. The cube of ice will weigh more than the cube of cork. Since density is weight (or mass) divided by volume, and the 2 volumes are the same, the ice is denser than the cork. Or, you could take an identical size sphere of each and lower them both into cold water. A visual inspection will show the obvious differences. The one that floats higher will be the one that's less dense (the cork).
What happens is that you can see that the density of a nail is more than the density of water and that the density of a cork is less than that of water.
Things that are less dense than the water they displace will float (like cork) Things that are more dense than the water (like a nail) sink.
Cork insulates, is water resistant and floats in water.
it floats
Cork does float in water because it's less dense than water.
yes it does. try to sink a cork. it doesn't sink but on the other hand a iron nail does.the higher the mass the more the density and so the object sinks.
A substance that has more density than the liquid will sink. With less density, it will float.
the density of the cork is lower than the density of the water- so it floats.
No. Cork floats because it is not only lighter than water, it doesn't absorb water. That's why cork is used to seal wine and champagne bottles.
If you dropped a cork in a container of water, the cork will most definitely float. As to the cork is lite, like a feather and it doesnt container much mass.
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.
