If an object has the same weight as water and is placed in room temperature water, it will typically remain suspended in the water without sinking or floating. This situation is known as neutral buoyancy.
Neutral buoyancy occurs when the density of the object is equal to the density of the surrounding fluid. In this case, since the object has the same weight as water, it means that its density is similar to that of water.
When an object is denser than the fluid it is placed in, it sinks. On the other hand, if the object is less dense than the fluid, it floats. But when the densities are equal, the object tends to remain suspended at a certain depth in the fluid, neither sinking nor rising to the surface.
So, if an object with the same weight as water is placed in room temperature water, it will typically hover at a particular depth in the water, neither sinking nor floating to the surface, due to neutral buoyancy.
