The same reason all vessels made of steel float - they're full of air filled compartments which keeps them buoyant.
While surfaced, a submarine's Main Ballast Tanks are also full of air. When the boat wishes to submerge, those tanks are emptied and filled rapidly with seawater. The boat's fixed ballast weight is a known variable, and variable ballast, in the form of water that can be pumped in or out of the boat, allows for adjustments in buoyancy control while submerged.
What else can I help you with?
When in water why is your body mostly under it?
because of your mass, you weigh more then the water and you sink, now the oxygenated red blood makes you float more and the air in your lungs also help you float.
Why cannot submarines go in deepest parts in oceans?
As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
Which weighs more you or your volume of water?
if you are talking about the same glass that had water in it and THEN froze, then my friend the weight is the same. Ofcourse this is correct only if while freezing, no water spilled out of the glass (because ice takes up more space than water.
Does feldspar float in water?
No, feldspar does not float in water because it is more dense than water. When placed in water, feldspar will sink to the bottom.
Can swimmer float more easily on a freshwater or an ocean?
The more salt there is in the water, the easier it is to float.
When oil leaks into the ocean why does the oil float to the surface?
Oil and water don't "mix" together in the normal sense, and oil is less dense than sea water. That makes the oil float because the water, which is more dense, pushes it (the oil) to the surface.Archimedes' Principle- a body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces. Therefor if one were to weigh a given amount of oil and the same amount of water, water would weigh more. Three stages of buoyancy are positive(floats) negitive(sinks) neutral(doesn't float or sink).
What force makes an object float on water?
An object floats on water when the buoyant force acting on the object is greater than the weight of the object. This buoyant force is exerted by the water displaced by the object, pushing it upwards. Objects that displace more water than they weigh will float, while objects that displace less water will sink.
Do objects float more in salt water or fresh water?
Objects float more in salt water compared to fresh water because salt water is denser. The increased density of salt water provides greater buoyancy for objects, allowing them to float more easily than in fresh water.
How does a ship stay on top of water?
a ship stays on water frombuoyancy which makes it float. the saltier the water the more buoyancy there is, enabling more weight to float on top
Will a marker float or sink in water?
I have a marker which float in water.
Does salt float in water?
Yes, salt can make water denser, causing objects to float more easily.
Does an egg float in water mixed with salt?
An egg does float in water that is mixed with salt, because salt provides more density in the water, and ,therefore, allows an egg to float.
