no
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.
It depends on the shape of the fork and the material from which it is made. Most non-metal (wood, plastic) forks will float. Metal forks will sink unless they are shaped to have a large enough surface area on the bottom.
Oil is denser than cork, so the cork would float.
Depends on the medium, and whether the ball is solid or not. A solid ball would float on mercury, sink in water. If it were hollow enough (or filled with, say, cork) it would float in water.
no
it floats
Wooden cork is less dense than the water and the iron is not.
If it is heaver than water (or what ever liquid you put it in) it will sink. Lead will sink. A cork will float.
Yes, a cork will often float on the surface of water, depending on the cork's density. But a marble will sink in water because of its weight. It will not float on the surface.
No. It may soften the cork but if anything hot water will make the cork expand.
no the cork will sink
All you would have to do is change the density of the cork or the water. An easy to do this is to create air pockets in the water. This will make the water less dense and it wont be able to "sink" underneath the boat. In other words, the water/air mixture created by the bubbles, will be less dense than the boat. And everybody knows that the denser object sinks, so then the cork will sink. The cork will stay sunk as long as you are creating bubbles.

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.
No a cork is made of a lightweight material and a glass of water isn't heavy.
