Submarine can sink or float.Submarine is fitted with ballast tanks that can be fitted with air or water hence varying its weight. To sink,ballast tanks are filled with water so that its Weight is greater than upthrust.
To float,compressed air is pumped into the tank displacing water so that upthrust is greater than weight of the submarine.
It displaces its own weight of water in which in floats
Submarine has tanks which are filled with air causing its density to be less than the surrounding water hence making it to float. When the submarine dives the tanks are flooded with water causing its density to be greater than water causing it to sink.

Submarines have tanks that are filled with air for it to float and for it to sink the tank is filled with water.
WhenFloatation tanks are filled with Water, the density of the submarine increases relatively to density of water hence it sinks…
Water are expelled from the tanks making the density of the submarine to be low.. Hence it floats
Submarines are fitted with air(floatation) tanks which can be filled with water or air. When the tanks are filled with air the submarine becomes lighter(less dense) hence floats and when they are filled with water the sub becomes heavier hence sinks.
