a submarine has a water tank. when the tank is filled then submarine sink in the water. and when the tank is empty then submarine float in water.
use the formula density= mass / volume
as mass increases(when the tank is full of water), the density of the submarine increases and it submerge into the water and vice versa.
Submarines sink or float by adjusting their buoyancy through the use of ballast tanks. When water is pumped into these tanks, the submarine becomes heavier than the water around it, causing it to sink. Conversely, to float, the submarine expels water from the ballast tanks, reducing its weight and allowing it to rise to the surface. This ability to control buoyancy enables submarines to navigate underwater and at the surface efficiently.
They use ballast tanks to contain sea water or air to control their depth
it will float as long as it is not fully covered water.
Arsenic is denser than water, so it will sink in pure water.
Submarines change their depth by use of ballast tanks. To dive, they open their tanks so that they become filled with water. They also angle their dive planes. To surface, they pump the water out of their tanks and fill them with pressurised air.
A fork will sink in water, as it is denser than water. The density of an object determines whether it will sink or float in water.
Asphalt is denser than water and will sink in water rather than float.
float
Float.
I have a marker which float in water.
a solid ceramic object would sink. however, if the object is displacing enough water proportional to it's weight, then it will float. If you put an empty glass bowl in the water, it will float; but if you allow water in, it will sink. This applies to ceramics.
i think it is ppeople because they float in salt water and sink in fresh water.
