Step 1
Which factor influences whether an object floats or sinks?
Answer
The fundamental factor that influences whether an object floats or sinks is its density compared to the density of the fluid it is submerged in. When an object is placed in a fluid, it will float if its density is less than that of the fluid, and it will sink if its density is greater. This principle is a reflection of Archimedes' principle, which states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced by the object.
Therefore, the correct answer is D: Density of object.
