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
What objects sink in the water?
Those objects that have a greater density than water will sink in the water. This comes from Archimedes' principle which states that a floating object displaces an amount of water equal to the weight of the object. If the object has a greater density than the water, then it would displace more water than is possible by its volume, so it sinks.
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 will an object sink if it's more dense than water?
The basis of foating or sinking is that an object sinks into water until it displaces a mass of water equal to the objects weight. Fot onjects with a density of less than water this occurs while some of the object is still above the water. For objects denser than water even when the object is completely under the water it has not displaces a mass of water equal to the obects weight - so the object continues to sink.
What is the relationship between mass of an object and thr amount of water that the object displaces?
No relationship at all. But there is a definite and direct relationship between theamount of water than an object displaces and the object's volume.
What is the density of a 12.5-gram object that displaces 16 cubed centimeters of water?
The density is 0,78 g/cm3.
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.
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.

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.
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.
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
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 an object that has a mass of 550 grams and displaces 25 mL of water?
550/25 = 22 grams per cc
What objects sink in the water?
Those objects that have a greater density than water will sink in the water. This comes from Archimedes' principle which states that a floating object displaces an amount of water equal to the weight of the object. If the object has a greater density than the water, then it would displace more water than is possible by its volume, so it sinks.
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 the weight of certain objects in water is zero?
If the object has the same density as water (specific gravity=1) then the weight of the object will be equal to the weight of water it displaces, so it will have neutral buoyancy and apparently weigh nothing. If the object has a lower density than water (specific gravity<water) then it will have positive buoyancy - like a piece of polystyrene foam - and will float on the top of water. In effect the excess weigh of the water it displaces is pushing it up. If the object has a higher density than water (S.G.>1) then it will sink, outweighing the volume of water it displaces. Google "Archimedes Principle". Note that the density of water can vary. Pure water has a density, or specific gravity, of 1.00, but sea water is denser due to the dissolved salt, which is why you can float more easily in the ocean. (The Dead Sea is an extreme example.) Alcoholic drinks are less dense than water, because of the ethanol they contain, and measuring their specific gravity gives a guide to their strength.
