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.
What else can I help you with?
Why is the reason an object floats in water?
If the volume of liquid the object displaces weighs more than the object, the object will float. The principle is buoyancy or specific gravity.
The specific gravity of an object is 14.5. The object displaces 4 mL of water. What is its mass?
The mass of the object is 58 grams (14.5 x 4 = 58).
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.
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.
Specific is the ratio of an object's density to that of water?
Specific Gravity.
What can you say about the specific gravity of an object that floats in water and the specific gravity of an object that completely submerges in water?
An object that floats in water has a specific gravity less than 1, indicating that its density is less than that of water. An object that completely submerges in water has a specific gravity greater than 1, indicating that its density is higher than that of water.
What happens to a object when placed in water if the density is greater than 1?
If the density of an object is less than that of water it will float. If it had a higher density it would sink. Since water has a specific gravity very close to 1 (it is exactly 1.000 at 4 °C but slightly less at other temperatures) an object with a specific gravity of 1 would sink. The mass of the water it would displace would be less than the mass of the object so the buoyancy forces would not be sufficient to let it float.
How much buoyancy will act when a boat displaces 600 kg of water?
The buoyancy force acting on an object is equal to the weight of the water displaced by the object. If a boat displaces 600 kg of water, the buoyancy force will be equal to the weight of 600 kg of water (water density x volume of water displaced x gravity).
What has a specific ratio of an object's density to that of water?
It is called the specific gravity.
What is the ratio of an object's density to the density of water is called the object's?
specific gravity
What is the term for the ratio of an object's density to that of water?
The term for the ratio of an object's density to that of water is specific gravity. It is a unitless value that helps determine whether an object will sink or float in water based on its density relative to water.
What is equal to the volume of water an object displaces?
The volume of water an object displaces is equal to the volume of the object itself, as stated by Archimedes' principle. This principle explains that the volume of fluid displaced by an object immersed in a fluid is equal to the volume of the object.
