How can you use the density of an object to predict whether it will sink or float?
First, what will the object be floating on? The principal to your question is: for an object to float, its density must be equal to or less than the density of the liquid on which it is to float. A brick will float on top of mercury, because mercury is more dense than the brick. A cork will float on water because the cork is less dense than water. The same works for gases. An aluminum baking pan will float on the invisible gas sulfurhexaflouride because SF6 gas is more dense than the baking pan.
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.
Why must water be displaced in order for a system to float?
A system (object) to float in water must displace enough water that equals (or exceeds) the mass of the system/object.
An objects density must be greater than what for the object to float?
An object's density must be less than the density of water,in order for the object to float.
How can you predict whether an object will sink or float in a liquid?
To predict whether an object will sink or float in a liquid, you must first examine the densities of both the object and the liquid. If the object is more dense than the liquid, it will sink. If the object is less dense than the liquid, it will float. For example, the density of water is approximately 1g/ cm3. The density of ice is approximately 0.92 g/ cm3. That is why when water freezes, the ice floats on the top rather than sinking to the bottom.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
Why do some objects float and others sink?
Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks. Density = Mass per unit Volume

Why does sugar water make objects sink?
For an object to float it must be less dense than the water/liquid that it's in. Adding sugar to water lowers its density because glucose molecules (sugar molecules) are less dense than water molecules. Therefore, putting an object into sugar water will make it sink.
What is the tendency of an object to float?
Whether a material in any state of matter (solid, liquid or gas) will float in a liquid (or a gas) depends on the relative densities of the materials. (Density is defined as mass divided by volume.) If the density of the object is less than the density of the liquid it is placed in, the object will float. If the density of the object is greater than the density of the liquid, the object will sink. If the densities are the same, the object will remain stationary assuming there are no other forces acting on it. For a few examples, a plank of wood is (generally) less dense than water, so it would float. A balloon filled with Helium is less dense than air, so it rises. A ball of lead is more dense than water, so it sinks. You can even float a liquid on top of another liquid if their densities are different.
What needs to be equal in order for an object to float in water?
For an object to float in water, it must displace the amount water equal to its own weight according to Archimedes.
How dense must an object be to float?
By definition, 1 gram of water will occupy one cubic centimeter. If the object to be floated on water weighs less per cubic centimeter it will float, and if it weighs more it will sink. *For an object to float in a liquid, it must have a lower density than the liquid. For example water has a density of one kilogram per litre and ice has a density of 0.9 kg/L, so ice floats; lead has a density of about 8-9 kg/L, so it will float in mercury (density of somwhere between 15 and 20 kg/L; please correct if you have the data).
What does density have to do with the ability to float?
Using water is an example, anything that is less dense than water will float on water. Anything that is denser than water will sink in water.
