You've been working for so long on measurement and density you're probably getting pretty good with your understanding. Using the words density, buoyancy, and submarine I want you to explain how a submarine works. Your explanation MUST be your own words and explain it in terms of density and buoyancy.

I think the way a submarine works is that it's just like a buoyancy vest they fill it up with air to make the density less than 1

I think the submarine looks like a scuba diving vest you can release and add density so it can rise or sink

I think that bouyancy helps the way a submarine works. When the tanks are filled with water the submarine begins to sink. But when the submarine is filled with air, it begins to float because it does not have much density to it. 9/30/2013 10:26:32 am
I think the way a submarine works is to have more air in it so it can float. Because when there is a hole poked or blasted out in a submarine it sinks because it is losing all the air that keeps it a float. it also goes under water too because it might work just like a diving vest because they can release air and fill air to rise or sink.

The density of the submarine should not be very high because there is alot of air in the submarine. it's bouancy kindof goes with how mr. c said a scuba diver works. The wieght from the submarine sinks it down but the engine pushes it in different directions (up, down, side , side)

I think you all have the pieces. Can someone make a detailed statement of how a submarine works?

If the density of a submarine exceeds the density of water the object will sink. Just like if you put a log in the water it will float because its density is less than the waters density. The buoyancy is what makes the submarine go up.

Good job Destiny, but I want to know how does it actually work.

A submarine uses air in chambers in the submarine making it less dense and buoyant allowing it to float above the surface. Also, it sinks by water filling those same chambers in the submarine to let it sink and therefore increase its density . The submarine is also being propelled by its propeller allowing it to move though the water.

I think the submarine can control its own buoyancy because it has ballast tanks. They can be filled with water or air. When filled with air, the submarine's overall density is less than the water it is in. But as the submarine sinks the ballast tanks fill with water and the overall density is greater than the water.

The buoyancy is what makes it float but it disposes more water Comments are closed.
