What needs to be equal in order for an object to float in water?
The weight of the object must be equal to the weight of the water it displaces in order for the object to float in water. This is known as Archimedes' principle. If the object is less dense than water, it will float; if it is more dense, it will sink.
What must the density of an object be for it to float in water?
The density of an object must be less than the density of water (1 g/cm3) for it to float in water. This means that the object will displace an amount of water equal to its own weight, allowing it 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.
What needs to be positive in order to float?
An object requires positive buoyancy in order to float, or the the upward force that a fluid exerts on an object less dense than itself. An example would be a person floating in the ocean, the person's body is less dense than the salt water, hence they float.
What 2 factors determine how heavy an object can be and still float?
The weight of the object must be less than the weight of the water it displaces (buoyancy force). Also, the density of the object must be less than the density of the fluid it is placed in (Archimedes' principle).

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

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).
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.
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.
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.
What For an object to float the mass of the water displaced must the mass of the object?
For an object to float, the mass of the water displaced must be equal to the mass of the object. This is known as Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object. When these two masses are equal, the object will float.
