It will sink when you put it in water. If it floats it has less density then water.

Does a heavier object or a lighter object experience a greater gravitational force?
I'm not exactly sure what you mean when you say "heavier" and "lighter". Does that mean the object's "weight" ? Could that be the same as the gravitational force on it ?
Calculate the weight of a solid object?
If the object is made of only a pure element or a pure compound whose density you could look up, you could multiply the density of the substance by the volume of the object, then, assuming you are on or near Earth's surface, multiply the product by 9.8 m/s^2.

If an object floats in water what can you conclude about its density relative to water?
In general the density of the floating object has to be less than that of water. BUt it is not always necessary to be so. Even dense material could be shaped in such a way it could float on water. The main thing is that the weight of the displaced water has to be more than that of the floating object. This is Archimedes principle.
How could you determine your buoyant force acting on you when you are floating in water?
Use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec).
What will an object do when it is placed in a liquid of greater density?
It could dissolve.Or it could float or sink. Which of the two it does depends on the mass of the liquid that it displaces which, in turn, depends on the shape of the object.
What will happen to a solid object made from matter with a greater density than water is dropped into water.?
It depends on the shape of the object. Otherwise you could not make metal ships.
How can the composition of an object be determined using density?
If you had an object whose composition was entirely unknown, you could not analyse its composition by density alone. There are an endless number of possible combinations of materials that would have any given density. However, in some circumstances density does allow you to determine composition. If for example, you have an alloy of copper and zinc, but you do not know the relative proportion of the two metals and you would like to find out, you could determine that proportion by measuring the density, since copper and zinc each have a different density, and the problem can be solved as a simple algebraic equation.
What could you do to an object to change its density?
Adding heat to the object if the object is a solid.
How could you define the density?
Density = mass of an object divided by the volume of that object. Its unit is mass per unit volume.
How could you determine the density of a king's crown?
water displacement
How could you find the the density of solids that float in water?
Determining density of an irregular objectDensity is mass per unit volume, so if you know an object's mass and the space it occupies, then you can calculate its density. If you had a scale, you could weigh the object to determine its mass. (Note that mass is not the same as weight, but the two are closely related insofar as we use weight to determine mass.) You could then carefully submerge it completely in water to determine how much water it displaced. That would tell you its volume. You would then divide the mass by the volume to get its density.But what if you don't have a scale? Can you still determine its density? I think you can.Place a known quantity of water in a graduated container. Carefully place the object in the container and note the change in the water level. Subtract the new water level form the old. That is the amount of water displaced by the object, which should be floating since it's less dense than the water. The weight of the water displaced by the object is equal to the buoyant force pushing up on the object.What does this tell us? Well, since the object floats, we know that the buoyant force is equal (but opposite) to the weight of the object. In other words, if we know the magnitude of the buoyant force, we know the object's weight (and therefore its mass)! Now, you can divide its mass by its volume, which you determined earlier by fully submerging it.Here's another wayDetermine how much water is displaced by the floating object. Then carefully fully submerge the object and record how much water is displaced. If you divide the first number by the second, you will know its relative density compared to the density of water! If the floating object displaces 100 ml of water and the fully submerged object displaces 150 ml, then the relative density is 100/150 = 0.667. Since the density of water is 1.00 g/cm3, that means the density of the object is 0.667 g/cm3.

How could you find the density of water?
density = mass/volume Determine the mass and volume of the water, and then divide the mass by the volume, and that will give you the density.
What are two methods of comparing whole numbers?
tell how you could use a number line to determine which of two numbers is greater
How is it possible that a can with a calculated density greater than 1.00grams could have floated in water?
Buoyancy is related to the amount of water displaced by an object, rather than it's density. You see this with ships all the time. The object may be much more dense than water, but if it can displace enough water to counteract the force of gravitation, it will remain afloat.
How could you determine if a simple gold is pure?
compare the samples density with that of pure gold
