A needle doesn't float because there is very little air in a needle. Metal is much more dense than wood, which is what most boats are made of. When a boat is made of metal, there are air stores inside of the boat that keep it afloat.
a big heavy steel ship floats on water because the volume is mostly air. trust me its true.
It is not the weight of an object that matters, but its density. If it has less density than the water (or other liquid on which it is placed), it will float.
ice cube floats in water because it is dense and heavy if u compare water to alcohol then an ice cube will sink in the alcohol because alcohol is less dense which means its light.

ans.1. wood can be float on oil because it is a thick, hard, and heavy object. 2.the bottle can not float on oil because it is not thick, hard, and, not heavy object. that's why it can not float
Needles don't float because metal is very dense and contains no air. A boat is either made of porous wood which is lighter than water, or metal with air reserves to keep it afloat.

No. For their size, diamonds are heavy and will not float.
no because they are too heavy to float .
Changzhou Zhihua Bearings Co., Ltd. is a professional heavy duty needle roller bearing manufacturer.They are the best heavy duty needle roller bearing supplier in this field. wish this can help you!

dissolved salt increases the density of solution than the density of heavy metal, which help the heavy substance to float
Things that float have a smaller density than water and things that sink have a larger density than water. Because a stone is heavy for its size it sinks but although a ship is heavier its mass is spread out over a larger area so its density is smaller and therefore it floats.

No, it is very soft and light and floats at the surface of water.
