There is no exact answer to this. If you could somehow get a large enough body of water to test it in, many of the gases in Neptune's atmosphere (e.g. ammonia) would rapidly dissolve in the water. Also Neptune is likely to have a dense stony or metallic core under its thick atmosphere, so different parts of Neptune might do different things.
However if Neptune had a homogeneous, insoluble in water, not chemically reactive composition, a sample of it would have a density less than the density of water an so would float, but Neptune does not have such a composition.
yes it would sink because its more dense than water
Scoria is a type of volcanic rock that is typically denser than water, so it will sink 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.
This depends on the density of this item: more denser than water-sink, less denser than water-float.
The gravel will float and the wax beads will sink
It will float. Its a rock. It actually depends on how much water you have, if you you tried float it in the ocean, it would obviously sink. But if you tried to float it on a gladd or bowl or water, it would float,
A magnet would typically sink in water as it is denser than water and does not have the buoyancy to float.
Gold is a very dense metal, so it would sink in water rather than float.
A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!
sink
a solid ceramic object would sink. however, if the object is displacing enough water proportional to it's weight, then it will float. If you put an empty glass bowl in the water, it will float; but if you allow water in, it will sink. This applies to ceramics.
it would sink
Blocks made of materials like wood or plastic would typically float in water, while blocks made of materials like metal or concrete would sink. The density and composition of the block determine whether it will sink or float in water.
it will float as long as it is not fully covered water.
Float - The density of water is 1.0, anything with a density less than this will float in water.
Arsenic is denser than water, so it will sink in pure water.
A paper clip is denser than water, so it would sink if placed in water.
