A body which is totally submerged in a liquid displaces a volume of water equal to the volume of the body.
To determine the density of an object, you need its mass and volume. If the object is oddly shaped, you can determine its volume by measuring the volume of water displaced when thee object is submerged in a container of water.
Two answers to this: 1. If the object floats on the fluid, then it displaces its own mass in fluid. 2. If the object sinks, it will displace its own volume in fluid.
Because most rocks are not made up of common geometric shapes, it would be difficult or impossible to find the volume of a rock using a ruler; there would be no easy way to measure the rock's irregular volume. However, by measuring the volume of liquid a rock displaces, its volume can easily be determined.
While many different units can be used to measure volume, the most common units for measuring volume are the cubic centimeter (cm3) = 1 milliliter (ml).
You would determine the volume of water it displaces and measure it.
Determine its volume by how much water it displaces, then divide mass by volume
The conclusion of the Archimedes principle is simply that the upward buoyant force that is experienced by a body immersed in a fluid, is equivalent to the weight of the fluid that the body displaces. This allows the volume of an object to be measured by measuring the volume of liquid it displaces after submerging. For any immersed object, the volume of the submerged portions equals the volume of fluid it displaces.
I would recomend measuring a pumpkin based on its mass, which can be found by weighing it (not that weight= mass, but weight can be used to determine mass as long as the pumpkin remains on Earth) You could also determine the volume by measuring how much water it displaces. I would stick to mass, though
by measuring the amount of water it displaces
You could weigh it. You can also determine its density by comparing it to an equal volume of water, but first you would have to determine how much water it displaces to determine its volume.
Submerge it in water and determine the volume (in cubic centimeters) that it displaces. That will be the volume of the nugget.
The technique of measuring minute changes in the volume of a part as a result of blood flow into or out of it.
You have to use a measuring cylinder and water.
You don't
volume of water an object displaces is equal to the volume of the part of the object inside it
A measuring jug is all you need for the volume and a mass balance is needed to determine mass.
