How do you determine if an object will float or sink when placed in water?

if the weight force down on the object is more than the upward push of the water then the object will sink, and reversed for rising

Explanation:

i found the answer online lol, hope this helps! :)

The space filling model of the water is shown in the figure given below in the figure, where δ+/ δ- represent the partial charge.

The water molecule consist of 2 hydrogen and one oxygen atom. The oxygen atom is the central molecule and the other two hydrogen are bind to the oxygen atom. The sizeof the oxygen is much bigger than the hydrogen and is more electronegative than hydrogen. Due to the elctronegativity, the oxygen pulls the electron and gain slight negative charge and the hydrogen gain slight positive charge and result in polarity.
