Relative density.
The density of an object is what determines whether it will sink or float in another substance. If the object's density is greater than the substance it's placed in, it will sink. If the object's density is less than the substance it's placed in, it will float.
Whether a pen floats or sinks in water depends on its material. A plastic pen will typically float, while a metal pen will likely sink. The density of the material determines whether an object will float or sink in water.
Solubility
The float determines how much gas goes through the carb.
The density of an object compared to the density of water determines whether it will float or sink. If the object is less dense than water, it will float. If it is more dense, it will sink.
no, what determines whether they will float or not is their density

You can float a dense solid material on water by shaping it into a boat-like structure that displaces enough water to create buoyancy. Another method is to attach a buoyant material, such as foam or a hollow container, to the dense material to increase its overall buoyancy.
A material with lower density than water will float, while a material with higher density will sink. The density of an object determines if it will float, sink, or remain suspended in water. Objects with a density less than that of water will float because they are less dense and therefore experience a buoyant force greater than their weight.
