When a subs surfaced, it's a regular ship. It displaces water (it's filled with air NOT WATER).

The air found in the submarine makes it float


Why does a submarine can sink and float in water?

A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.


How do submarines float and sink in water?

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.


Will a steel bar float in water?

No, a solid steel bar will sink in water because steel is denser than water. Only objects with a lower density than water will float.


Will 7.81 g of steel float on water?

No, 7.81 g of steel will sink in water because steel is denser than water. Steel has a higher density than water, so it will not displace enough water to float.


How do you make a plastic bottle submarine float then sink and float?

put water in to let it sink... then put air into it to let it float...


The buoyancy force on a submarine submerged in the ocean equals what?

The buoyancy force on a submerged submarine equals the weight of the water displaced by the submarine. This force acts in the opposite direction to the gravitational force, allowing the submarine to float or sink in the water.


Will steel pipe float?

Steel pipe will not float in water because it is denser than water. The density of steel is significantly greater than that of water, which is why steel sinks. However, if the steel pipe is hollow and filled with air, it may float depending on its overall buoyancy, which is determined by its shape and the ratio of its volume to its weight.


Why would a solid steel marble sink and a steel bowl float in a bathtub of water?

it is hollow so it will float


Will the submarine sink or float when its weight is equal to the upthrust acting on it?

The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.


Why can steel ships float on water although steel is denser than water?

Steel ships float on water because their shape is designed to displace enough water to create a buoyant force that is greater than the weight of the ship. This buoyant force allows the ship to float despite the steel being denser than water.
