Best Answer

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.

What factors determine wheter or not an object will float?

Sinking or floating are determined by the density of the object.


What 2 factors determine how heavy an object can be and still float?

The density of the object and the density of the liquid. The object must be less dense than the liquid to float.

How can you use density to determine if an object will sink or float a fluid?

If the density of an object is lower than water then it will float, if the density is higher it will sink.

Is it true that when the weight of an object is less than the density of water that object the object will float?

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.


How can you use density to determine whether an object wil float or sink in a fluid?

If the density of the object is less than the density of the water it is placed in, the object will float and vice versa.

Does mass determine whether an object will float or sink?

The density of the object (mass/volume) compared to the density of the liquid.
