What is true about the mass and volume of all floating objects?
The volume of liquid displaced has the same mass as the floating object.
Does the amount of water displaced by an object depend on its mass or its volume?
Volume
What is the formula for finding the density of a liquid?
Density of a object displaced in water = mass of object/volume of liquidTherefore Density = mass/volumeUnit of Density is 1g/1000 cm3
What is the density of A rectangular wooden block that measures 10 cm by 4 cm by 2 cm when placed in water and it is floating horizontally with its bottom face 1 point 65 cm below the surface?
It is 0.825g/cm^3. Use the area of the wood to find the area of the water displaced with a depth of 1.65. This will give you the volume of the water and multiply that by it's density(1000kg/m^3) to reveal the mass of the water. The mass of the water should be equal to the mass of the wood. Divide this mass by the volume of the wood(not the water segment), which will give you the density of the wood block. Be careful with the unit conversions, you may do the right math, but still have the wrong answer.
How do you find the mass of an irregular object?
you use the water displacement test. the mass of the displaced water is equal to the mass of the object. because the density of water is one, this means that the volume of the water is equal to the mass of the object * * * * * That is only true if the body floats. Two blocks of different metals, but of the same size will displace the same volume of water. Their masses will not be the same.
What is true about the mass and volume of all floating objects?
The volume of liquid displaced has the same mass as the floating object.
Which one will determine how much water will be displaced - mass or volume?
Mass will determine how much water is displaced by something that floats. Volume will determine how much water is displaced by something that does not (that sinks).
What do you notice about the density of floating objects?
Usually the density of floating object will be less than that of the liquid in which it is floating. But exception is that ship made up of iron will float in less dense water. Becasue a large amount of water will be displaced due to the specific construction of the ship. The weight of the displaced water will be more than the floating ship.
How do you find the mass of an object based on the displaced water?
To find the mass of an object based on the displaced water, you can make use of Archimedes' principle. Measure the volume of the water displaced by the object, and then multiply it by the density of water (usually 1 g/mL). This will give you the mass of the object.
What relation do you find between the weight of the floating body and the waight of water that is displaced?
They are equal.When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down.Note - relation between volume(v) mass(m) and density(d) : d = m/v
How can you tell the mass of the water displaced?
use the water displacement method.
How do you measure buoyancy?
place an object in a container with a fluid and find the amount of water it displaced. then find the mass of the object. then multiply the mass by the amount of displaced water♪
Describe Archimedes' Principle and how it is used to determine whether or not an object will float in a fluid?
The Principle states that the mass of a liquid displaced by a floating body is equal to the mass of that body. So if you fill a tumbler up with water to the brim, put an object into it, weigh the water that has been pushed out of the tumbler, and compare that with the weight of the object, you'll know whether it floats ot not. If you're doing this with a large object like a ship you'd need to calculate by measurement how much water is going to be displaced by the weight of the ship (also calculated). Hopefully, it's be the same, or your ship will sink.
How is Archimedes related to buoyancy?
Archimedes stated that the mass of liquid displaced by a floating body equalled the mass of that body. One can deduce from this that if the displacement is less than the mass of a body then that body will sink.
Why is ship floating on the water but it is made of metal?
Because the volume of water it displaces weighs more than the ship. Archimedes principle says that the upwards force on the ship is equal to the weight (mass) of fluid displaced - so the ship floats
What does the volume of displaced water equal?
It equals the mass of the object placed in it.
Does the amount of water displaced by an object depend on its mass or its volume?
Volume
