Density and shape.
It is easy enough to make a boat out of iron. We all know that Iron is heavier than water, but by shaping it we can make the shape so that its volume inside could hold more weight of water than its own weight. That way, it will float.
If a materials density is less than the density of water, then it will float no matter what.
No, volume alone does not determine if an object can float or sink. It depends on the density of the object compared to the density of the fluid it is placed in. If the object is less dense than the fluid, it will float; if it is denser, it will sink.
You can determine if an object will float or sink by comparing its density to the density of the fluid it is placed in. If the object is less dense than the fluid, it will float; if it is more dense, it will sink. By using Archimedes' principle, you can calculate the buoyant force acting on the object to determine its buoyancy.
Density
i think buoyancy
If the density of an object is lower than water then it will float, if the density is higher it will sink.
Comparing the density of an object with that of a liquid will determine whether the object will float or sink in the liquid. If the object is less dense than the liquid, it will float; if it is more dense, it will sink.
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
Shape and density
The main factors that determine whether an object will sink or float are its density compared to the density of the fluid it is in. An object will float if its density is less than the density of the fluid, and it will sink if its density is greater. Other factors that can affect whether an object will sink or float include its shape and the presence of any air pockets or empty spaces within the object.
An object will float in water if its density is less than the density of water. If the object is denser than water, it will sink.
To determine if an object will sink or float in water, you compare the density of the object to the density of water. If the object is denser than water, it will sink. If the object is less dense than water, it will float. The principle of buoyancy, which states that an object will float if it displaces an amount of water equal to its weight, also plays a role in determining whether something will sink or float.
If it is lower it will float
