Answer: An object denser than water will sink in water.
Explanation: The ability of an object to float or sink in water depends on its density. An object that is denser or heavier than water will sink in water while an object that is less dense or lighter than water will float in water. For example a piece of stone will sink in water because it is denser than water while a plastic container will float in water because it is less dense than water.
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
