How can water displacement be used to measure the density of irregularly shaped solid?

Density is mass per unit of volume of a material. If you have a solid of homogeneous material, weigh it. Then take a container filled to a given level with water. Immerse the object and note the new water level. Compute the difference in level and you'll know how much water was displaced by the object. This is equal to the volume of the object. With its volume and mass known, divide the mass by the volume to get the mass per unit of volume. This will be the density of the material your object is made of.
Let's say you have a "funny-shaped" silvery metal object, and it displaces 100 cubic centimeters of water. If it weighs 270 grams, it will have a density of 270 grams / 100 cubic centimeters or 2.7 grams per cubic centimeter. Your object may very well be made of aluminum, as aluminum has a density of 2.7 grams/cc.

So for a known mass, and a known density, you can work out the volume of an object, and displacement is a very easy way of controlling both mass and density, since you can weigh the liquid, and using the same equation, work out density.
OR you put the gold crown or whatever you are trying to find the volume of into the bath, see how much the water rises, and eureka! you have the volume.

Let's say you want to measure the volume of the toy car- fill the measuring cup with enough water to fully submurge the car but don't put it in yet. Write down the amount of water in the cup before you put the car in. Put the car in. Now write down the amount of water in the cup after fully submerging the car (there will be more). Now subtract the amount of water before the car from the amount after the car. That is the volume of the car.

∙ 11y agoYep, it can! Try it with a cube, its easy. The only problem is that it might not work as well as just finding the volume

What to scientists use to measure the mass of an irregularly shaped solid?
A balance is used to measure the mass of an irregularly shaped solid.
How to calculate density weight for aluminum?
Get a sample of the metal. Use a scale to find its mass. If it is shape is that of a rectangular solid (box) measure length, width, and height and multiply to find volume. If it is irregularly shaped, use the water displacement method to find its volume. Divide the mass by the volume to get the density.
How will you find the volume of an irregularly shaped object that would dissolve in water?
Use volume displacement method.
When is displacement used?
It is used to find the volume of an irregularly shaped object. An object dropped into a volume of water will displace an equal volume of water.
How would you find the density of an irregularly shaped object such as a rock?
Weight it. Find it's volume. (hint - how much water does it displace). Divide.
What is formula for calculating an object's density?
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
How do you determine the volume of an irregularly shaped object that floats?
You can push it under water / under the liquid's surface, and measure the displacement of liquid.

What is the name of the method by which the volume of an irregularly shaped object is found?
the water displacement method

How do you calculate the density of an irregularly shaped object which is less dense than water?
Force it below the surface of water and measure the force required.
How will you find the volume of an irregularly shaped object that would dissolve in water?
Use volume displacement method.
How can you determine the identity of an irregularly shaped solid that is soluble to water?
you would use the water displacement theory
How do you find volume when mass and density are not givin?
It depends on the way the question is asked. If you are dealing with a cubic or rectangular object, you measure the length, width, and height, and multiply them. If it is a spherical or irregularly shaped object, you could used water displacement to find its volume. If it's a liquid, you could use a graduated cylinder to measure its volume.
Finding the volume of a solid when would water displacement be helpful?
When you are trying to find the volume of an irregularly shaped object.
How do you describe the procedure for determining the volume of an irregularly shaped object when using water and a graduated cylinder?
Volume displacement.
What do you call the procedure that helps you find the volume of an irregularly shaped object using a graduated cylinder?
It is the displacement method.
