Which of the following substances will sink in water?

When the weight force on an object is countered by the water's upward push, the thing floats. Water exerts an upward force proportional to the volume of the submerged object; water depth or volume have no bearing on this upward force. The object will sink if the downward force of the weight is greater than the upward force of the water on it. The thing will rise if the contrary is true because rising is the opposite of sinking.
