No air or any form of gas will always rise to the surface (as a bubble)
If an object has air in it than no it will not sink in water because air is less dense than water so it will rise in water.
There is air in it.
Cold water and air tend to sink because they are denser than warm water and air. As they cool down, the molecules become more tightly packed together, increasing their density and causing them to sink. This creates a convection current where colder, denser fluid or air sinks while warmer, lighter fluid or air rises.
It's possible that a ship of steel will not sink as well. But if it will sink, it would be because the density of steel is greater then the density of water, while air's density is lower then water's.
The ice have air pockets so the air makes it floats
No they sink to the bottom because they hold no air.
The sink gurgles when the water drains because air is being pushed through the pipes along with the water, creating a bubbling or gurgling sound.
A weighted air-filled balloon sinks in deep water because the weight of the added material overcomes the buoyancy provided by the air inside the balloon, causing it to be denser than the surrounding water and therefore sink.
Apples float in water because they have air pockets in their flesh, making them less dense than water. Pears sink because they have a denser flesh and fewer air pockets, causing them to be heavier than water.
Basketballs are filled with air, and won't sink w/o some serious help.
You take of the air and so it will sink because the water will move aside and let it go dowm
Objects that are heavier than water will sink down, such as metal objects or rocks. Additionally, liquids and gases can sink down into a denser medium, like oil sinking down in water or hot air sinking down in cooler air.
