I assume you mean a solid that has the same density as a liquid that it is submerged in. If they have the same density, then when the solid is in the liquid, there is exactly zero net force acting on it (weight of solid object is perfectly balanced by bouyant force), so the solid object will just "sit there," assuming there are no other outside forces acting on it (ex. currents, etc.). If the object is dropped into the liquid, for example, it will move deeper into the liquid (because it has downward momentum from the drop) until resistance from the liquid stops its motion, at which point it should remain stationary.
The solid object would be "neutrally buoyant" with respect to the liquid you placed it in. If you placed it in fairly gently, it would float at the surface (as opposed to ON the surface, like a cork in water for instance).
If you pushed the object below the surface it would float at the level you pushed it down to (imagine a diver using their weight belt and flotation vest to maintain a fixed depth: not quite the same thing but the effect is the same).
However, depending on the depth of the liquid, you would also need to take into account the "pressure gradient". This means that as the pressure in the liquid increases with depth, it becomes more dense. So, there will be a point in your liquid where the density of the liquid rises above the density of the solid object. The solid object would therefore "float" back up to this point if forced any deeper.
The density will increase. Think about water, when it turns to solid, the ice floats which means it just became less dense then the liquid. hope this helps
You have not asked a question. That is a statement.
It keeps moving until friction slows it down, then hovers motionlessly forever in the fluid, neither floating nor sinking. Unless the are waves in the water or something is moving etc.
melt
the density of the substance decreases
The solid cannot float in this liquid.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
It sinks in the liquid. A steel bolt has a density greater that that of water. Drop it in water, it sinks.
-Solid and a liquid? -A liquid and a gas? -A solid and gas? from roop
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
When a substance changes from a solid to a liquid and vice versa, its density changes.
This change in the state of matter (liquid to solid) is called freezing.This change in the state of matter (solid to liquid) is called melting.They are physical change, the chemical nature of the molecules is not changed.
It evaporates?
The solid changes into a liquid
It "condenses".
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
It can melt into a liquid, it can be juiced,
It can melt into a liquid, it can be juiced,
The solid cannot float in this liquid.
they get further apart
it heats up
it melts
