A submarine has "ballast tanks" which can be filled with water to make the vessel heavier (total density greater) than water and dive to required depth. These ballast tanks can also be filled with air (compressed air is kept on board for this) to make the vessel lighter and rise to the surface
What else can I help you with?
Will Asphalt sink or float in sea water?
Asphalt, being denser than water, will sink when placed in sea water. This is because the density of asphalt is about 1.36 g/cm³, while sea water has a density of around 1.025 g/cm³.
Is asphalt sink or float if you placed in sea water?
Asphalt is less dense than water, so it will float on the surface of seawater. This is because asphalt is a petroleum-based material that is made up of hydrocarbons, which are lighter than water.
Can you float in glucose or sea water?
You can float in sea water due to its buoyancy from the salt content. However, you would not float in glucose because it is denser than water.
Do you float in sea water?
Yes, objects tend to float in sea water due to its high density compared to fresh water. The salt content in sea water makes it denser, providing more buoyancy for objects to float.
Why do you sink in the water but ships do not?
Because normally when ships sail they start in a harbour near the sea. The sea is filled with salt witch allows it to float much easier when people swim the swim in a pool or river with no salt in it. I think.
If a sumbarine submerges what is it doing?
A submarine is a sea going vessel that is designed to run submerged or on the surface of the sea. Basically, by filling ballast tanks with sea water, the submarine will sink, and by blowing out the sea water from the ballast tanks with compressed air, the submarine will float on the surface.
Is mercury sink or float if you placed in sea water?
Mercury is a heavy metal, it will sink in sea water.
HOW can a submarine float in water sink in the sea or come up to the surface?
The buoyancy of a submarine may be varied by having ballast tanks, into which either water or compressed air may be added or subtracted to vary the average density of the boat. Thus it will have a variable buoyancy.
Will the object sink or float in water?
Whether an object will float or sink in water will depend on its volume and weight. If the weight of the displaced water is more than that of the body, the body will float. On the other hand if the weight is the displaced water is less than that of the body, the body will sink. Again if both of them are equal, the body will partially sink. Sea water contains salt. So its density is more and consequently, the weight of the sea water is more. So there is more chance of a ship to float in sea water than in river water. ADD: It depends on the density of the object. If an object is denser than water, it will sink. If it is less dense than water, it will float.
Will Asphalt sink or float in sea water?
Asphalt, being denser than water, will sink when placed in sea water. This is because the density of asphalt is about 1.36 g/cm³, while sea water has a density of around 1.025 g/cm³.
Why things float in the dead sea?
becuase there is such a high salinity that the water is too thick for anything to sink in it
How do submarines float sink and stay in the middle of the sea or ocean?
They use ballast tanks to contain sea water or air to control their depth
What is a sea going vessel?
its anything that can float in sea like a submarine,ship, yacht etc
Why did the old island in Hawaii sink under the sea?
The islands do not float, and cannot sink. Think of the islands as being REALLY tall mountains- that start on the sea floor and go up from there. Part of the mountain is above water.
What is the density of the water the sea lions live in?
Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
Is asphalt sink or float if you placed in sea water?
Asphalt is less dense than water, so it will float on the surface of seawater. This is because asphalt is a petroleum-based material that is made up of hydrocarbons, which are lighter than water.
What body of water that is so salty that you can not sink?
The Dead Sea is the body of water known for its high salinity levels, which make it nearly impossible to sink. The dense salt content creates greater buoyancy that allows individuals to float easily on the surface.
