Does weight or density play a huge role in determining whether or not an object will break surface tension?
Density plays a bigger role.
How can the density of a body lighter than water be determained?
If a object with little volume floats on water its density is less than water.But should consider to avoid effects of surface tension
What most influences whether or not an object will float?
An object's density influences its buoyancy, thus determining whether or not an object will float
What is the difference between surface and density?
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
What influence will the size of the surface and the mass of a floating object have on the floating ability of the object?
The density is important; for floating an object must have a density under the water density (1 g/cm3).

What has to have more density for an object to float on water the object or water?
Normally the water - to float and object has to displace a volume of water equal to its mass. If its density is greater than that of water, the maximum mass of water it can displace is its own volume which, as the water is less dense that it, will have less mass than the object and it will sink. However, for small light objects the surface tension of water comes into play - it is possible to float a steel sewing needle (with a density greater than water) on water by gently dropping a clean needle on its side onto the water surface so that it does not break the surface tension. With a needle floating, adding a few drops of washing up liquid to the surface reduces the surface tension and the needle will then sink.

How could it be possible that an object with a density greater than that of water could float in water?
There are two ways to make an object with a density greater than water float on it: 1) reduce its density, for example by hollowing it out or adding further structures with a density [much] less than that of water so that it can displace a volume of water equal to its own weight and still have some of its structure above the surface of the water; or 2) Use the surface tension of water so that the object floats - dropping a steel sewing needle on its side very gently onto water will prevent it breaking the surface tension of the water and it will float, until such time as the surface tension is broken, eg by adding a few drops of washing up liquid or agitating the surface, when the needle will sink. (The needle needs to be clean.)
Why do you have to measure the mass before determining the density?
You have to measure mass before determining density because of the equation D=M/V. If you are somehow unable to find the mass, you can always use an inverse of the equation if you have the measurements of volume and density, which would equal M=DxV.ANS2:You don't need to know the mass if you can measure the object's buoyancy in a liquid whose density is known. For instance: If 10% of an object protrudes from the surface of a liquid with the density of 1g/cm3 (water at 4 deg C) then you know that the density of the object is 10% less than the density of that liquid.
SURFACE TENSION?
Te tension on the surface of an object.
What most influences whether or not an object will float?
An object's density influences its buoyancy, thus determining whether or not an object will float
What is the difference between surface and density?
You cannot use surface area to calculate density. Density is a calculation comparing TOTAL area and weight of an object. In short you must use the total volume of the object when calculating the density.
An object that floats on the surface of water?
the amount of density
Will an object sink in water if it has a high density?
It will sink if its density is higher than the water's density, typically 1.0 gm/cm³. Exceptions are very small objects that cannot break the surface tension of water and objects that are shapes such that water is excluded from their interior (ships).
What influence will the size of the surface and the mass of a floating object have on the floating ability of the object?
The density is important; for floating an object must have a density under the water density (1 g/cm3).
How does a flat shaped object float?
Well it depends on the density of the object and the density of the liquid that it is placed in. The object produces a buoyant force that lifts it to the surface of the liquid.
