Will a Dense Green Object Sink in a Sealed Water-Filled Pipe?

In summary, the conversation discusses a closed and well-sealed pipe structure filled with water and a green object that has a density of 1.2, greater than that of the water. The question is whether the green object will sink in this situation. One person believes it will sink due to the overall weight being heavier in the pipe with the green object. Others discuss the possibility of toppling and the experiment's scope, which is to focus on what happens inside the pipe.

Please see the below image, it is a closed and well sealed circulated pipe structure, fully filled with water and no air inside. The density of that green object is greater than water (say 1.2 while water is 1). In this situation, will the green object be sunk? Better with some explanations, but not only yes or no, thanks!

what do you think and why ?

Thanks for your reply, I think it will be sunk, as the total weight in the pipe with green object is heavier than the other pipe. I just want to confirm this and no need to consider other things.

That is the reason why the whole thing would fall over, not why the green object sinks inside.

Sorry, do you mean water in both pipes will fall, and vacuum creates at top??

He left out the clamps for the experiment in the diagram. Did we not automatically take that into account? If the possibility of toppling was meant to be discussed, wouldn't there have been a table top in the diagram?
@Meteor73 that looks an OK argument - straight out of Archimedes

:biggrin: Thanks Sophie, this is not the scope of the experiment. We can assume the pipe structure is well fixed, and just focus on what happen inside the pipe.
 

1. Will a dense green object sink in a sealed water-filled pipe?

The answer depends on the density of the object and the density of the water. If the object is more dense than the water, it will sink. If the object is less dense than the water, it will float. The color of the object does not affect its buoyancy.

2. How does the density of the object affect its ability to sink in a sealed water-filled pipe?

The density of the object is the main factor in determining whether it will sink or float in water. Objects with a higher density will sink, while those with a lower density will float.

3. Can a sealed water-filled pipe affect the buoyancy of a dense green object?

Yes, a sealed water-filled pipe can affect the buoyancy of a dense green object. If the pipe is filled with a liquid that is more dense than the object, it will increase the object's buoyancy and make it more likely to float. On the other hand, if the pipe is filled with a less dense liquid, it will decrease the object's buoyancy and make it more likely to sink.

4. Is the shape of the dense green object important in determining its buoyancy in a sealed water-filled pipe?

Yes, the shape of the object can affect its buoyancy in a sealed water-filled pipe. Objects with a larger surface area will displace more water and be more likely to float, while objects with a smaller surface area will displace less water and be more likely to sink.

5. Why is the water in the sealed pipe important in determining whether a dense green object will sink or float?

The density of the water is crucial in determining the buoyancy of an object. If the water is more dense than the object, it will provide more upward force and make the object more likely to float. If the water is less dense than the object, it will provide less upward force and make the object more likely to sink.
