Mass and volume are related to the sinking and floating of an object through their density. An object will sink if its density is greater than the density of the fluid it is placed in, and will float if its density is less than the density of the fluid. The relationship can be expressed as density = mass/volume.
Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of a reference substance (usually water). Relative density is dimensionless and is often used to identify substances or determine their purity based on their comparison to a standard substance.
The relative density of an object is determined by comparing its density to the density of water. It is calculated by dividing the density of the object by the density of water. If the relative density is less than 1, the object will float in water; if it is greater than 1, it will sink.
An object will float in a fluid if its density is less than the fluid's density. If the object's density is greater than the fluid's density, the object will sink. If the object's density is equal to the fluid's density, it will be suspended at a specific depth.
If the density of a substance is greater than the density of water, it will sink in water. If the density of a substance is less than the density of water, it will float on water.
