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.
Will an object with the density of 3.7 float and why?
No. To float density must be less than 1 (the density of water).
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.
What makes something float on water?
Salt makes most things float on water. So just add a good amount of salt. Depending on the size of the objectAnswer:Objects will only float in liquid that is denser than the object. In the case of water this means the density of the object must be less than 1 g/cm3, the density of water at its highest density at about 6oC.If the object is not a solid block of material the density is the density of the volume of the object. In the case of a light bulb (as an example) the density of the components of the bulb if crushed will exceed the density of the water and sink, but in the shape of an intact bulb, the density is less than that of the water and the bulb will float.
Can you use volume alone to predict whether an object will sink or float?
Calculate the density (mass divided by volume) of your object. If the density is less than that of water - which has a density of about 1000 kg per cubic meter - then it will float; if the density of your object is more, it will sink.

An object's density must be less than the density of water,in order for the object to float.

No. To float density must be less than 1 (the density of water).
Would a substance float if its density is 1 gram per ml?
Less than that of the substance it is floating on.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
What must be the density of an object with a mass of 5000 grams if the object is to float in water?
In order for an object to float on water, its overall density must be less than 1 g/cc.That goes for a shirt-button, a super-tanker, or an iceberg the size of Texas. The object's massmakes no difference.
How do you know if an object will sink or float in water based only their densities?
If a volume can be neglected the object must have less density than water.
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 a penny sink in water?
water has a density of 1. For something to float, the density of the object would have to be under 1, and to sink, it must be over 1. If it is exactly 1, then the object will remain suspended in the water. A penny has a density of over 1, so it sinks in water.
