What is the density of a 12.5-gram object that displaces 16 cubed centimeters of water?
The density is 0,78 g/cm3.
If a 25kg object is submerged and displaces 20kg of liquid the object will?
Sink. It's density will be greater than water, which is 1 kg per litre.
What is the density of a solid object that has a mass of 15.0 g and displaces 11.6mL of water when placed into a graduated cylinder initially containing 20.0 mL of water?
density of object = 15.7g/15.9 ml = 0.987 g/ml. At 4ºC the density of water is 1.0 g/ml so this object will FLOAT in water at that temperature. Even at room temperature, the density of water is slightly greater than 0.987, so this item will still "probably" float.
How does the density of an object that sinks into a fluid compare to the density of the fluid?
Oh boy. Density is the mass per volume...grams per cubic centimeter, tons per cubic yard, whatever. Water's density is one gram per cubic centimeter. An object with lower density than water will sink into water until the number of cubic centimeters corresponding to the mass of the object are below the surface of the water. If the object is 100 cubic centimeters and it weighs 50 grams, half of it will be below the surface and half above. This is buoyancy, or "floating." Cool so far? If an object's density is more than one gram per cubic centimeter, the whole thing will be below the surface of the water. Because the water can't support the weight of the item, it will sink to the bottom given enough time. If it sinks, its density is greater than water...but without weighing it, we can't say how much greater because an item with mass of 5 grams and density of 1.1 grams per cc will sink as surely as a 300-pound anvil with density of 7.2 grams per cc. It just won't do it quite as fast.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
A 0.8 kg object displaces 500 mL of water. What is its specific gravity?
the specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object. The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density. .8kg * 1000g/kg = 800 grams so, 800g/500ml = 1.6grams/mL this is the density. So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.

Which object will displaced more water if object A equals 500grams and a density of 5 gram per cubic centimeter object B equals 650 grams and density of 65gram per cubic centimeter?
Object A, 500g/5g/cm3 = 100 cm3 Object B, 650g/65g/cm3 = 10 cm3 Object A displaces more water.
How does the density of an object affect it as it sinks through water?
It's difficult to tell what you are asking. If the question is concerned with the bouyancy of the object, it will sink if it first displaces its volume of water, or will float if it first displaces its weight in water. Since density is mass per unit volume, objects with an average density greater than water will sink.
How do you calculate the density of an irregularly shaped object that floats in water?
If an object floats in water, we can immediately conclude that it is less dense than the water. So, we've already gained a bit of information. But can we learn more? Yes. We can further "ballpark" our estimate of the object's density through additional observation and deduction. About how much of the object is submerged? If, say, 75 percent of the object is under water, we can then say that its relative density -- that is, its specific gravity -- is about 0.75. In other words, it has a density of 0.75 grams per milliliter or, equivalently, 0.75 grams per cubic centimeter. (Note that the density of water is 1.00 gram per milliliter.) But can we do better? I think so. If we measure the volume of water displaced by the object when it is placed into the container of water, we can calculate the weight of the object, because its weight will be equal to the weight of the water it displaces. If the floating object displaces, say, 100 milliliters of water, then we know it weighs 100 grams, because, as noted above, the density of water is one gram per milliliter. But we're not done. To calculate an object's density, we must know its volume as well as its mass. From the measurement above, we know the object's weight , but we don't know its volume, mainly because of its irregular shape. But if we carefully push the object completely under water, it will displace an amount of water equal to its volume. Let's say that when we submerge the object fully, it displaces 130 milliliters of water. We therefore conclude that its volume is 130 milliliters, which is equal to 130 cubic centimeters. Since the object weighs 100 grams and has a volume of 130 cubic centimeters, its density is 100 grams/130 cubic centimeters = 0.769 g/cm3.
What is equal to the volume of water an object displaces?
volume of water an object displaces is equal to the volume of the part of the object inside it
How does density affect buoyancy?
Ignoring shapes (using cubes), density (mass/volume) greater than "water" means it sinks. The floating object displaces its weight of the buoyant "object" (water, etc.)when it floats, but displaces its volume when it sinks.
If a 25kg object is submerged and displaces 20kg of liquid the object will?
Sink. It's density will be greater than water, which is 1 kg per litre.
