No weight is a measurement of the gravitational pull of an object the density is how tightly packed the matter is.
Think of a co2 cartridge it is co2 densely packed.

How is weight different than density?
density is weight compared to size and how much mass is in object weight is just weight.
If the weight of an object is greater than the weight of the water that it displaces what will happen?
It will sink, because it has a greater density (the same volume weighing more)
Why does that a small pin sinks in water?
Because the pin is more dense than the water. Density and weight aren't the same thing. A feather, for example, has less density than the water so it would float.
Why it is easier to float in sea water than in fresh water explain this in light of density?
Salt water has a greater density, therefore, it can support a larger weight (for an object of the same volume).
Why does the object with same volume and different mass has a greater density?
an object is more dense if there is more weight in the same area, its because of the amount of particles and the weight of the particles. eg, 1cm cubed of gold would weigh alot more than 1cm cubed polystyrene, so gold is more dense

Do feathers weigh more than bricks or cheese?
They all "weigh" the same: one pound. They're equal in weight which is different from density. :-)
Does density equate to weight?
Yes, it does. Higher density means being more dense than something else. In that light, that makes it a relative or comparitive term. But you are correct. Higher density means something is more dense than something else.
If the weight of an object is greater than the weight of the water that it displaces what will happen?
It will sink, because it has a greater density (the same volume weighing more)
Is the density of 8 mL of water greater than equal to or smaller than the density of 4 mL of water?
It depends upon the temperatures and purity of the two quantities of water. If they are both at the same temperature and both have the same purity, they will both have the same density as density does not depend upon the volume, but the substance itself. If they are at different temperatures, or have different purities, then they will have different densities, but which would be greater would depends upon which has which temperature and which purity.
How can a gallon of milk can have different density than a gallon of water even though it has the same volume?
Though they have same volume,they have different masses.
How does the density differ between a glass and a plastic cup that have almost exactly the same volume?
Higher molecular interaction force contribute to higher density. In additional, higher molecular weight give tendency to higher density at same intermolecular force. Even plastic had different density, some plastic is lighter than water but some can be twice heavy, PVC for example.
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.
What does the weight of an object that floats have the same value as?
The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
Water weight ice weight?
Water's weight, when frozen into ice stays the same, but the density of water is much higher than ice's, since Ice has the same weight and contents of Water, but takes up significantly more space.
Why does that a small pin sinks in water?
Because the pin is more dense than the water. Density and weight aren't the same thing. A feather, for example, has less density than the water so it would float.
Is 238 gram bigger than 237ml?
Both the terms gram and ml is different from each other; and correlated with density. When we multiply volume into density then we get mass of that body. So whether or not 238 gram is bigger than 237ml is totally based on the density of that body.eg: for mercury(density-13.6gm/ml), weight of 238 gram is lesser than 237 ml.for oil(density-0.9gm/ml), weight of 238 gram is bigger than 237 ml.
