The displacement method is a method for measuring the volume of a solid. The solid is immersed in liquid and the level of the liquid before it is immersed is subtracted from the level of the liquid after it is immersed to get the volume of the solid.
water displacement
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.
Yes, the volume displacement method can be used for objects that float. This method calculates the volume of an irregular shaped object by measuring the water displaced when the object is submerged. The difference in water levels before and after submerging the object is used to find the volume of the object.
Use the water displacement method
First 'weigh" the ojbect on a scale. this gives the mass. 2nd use the water displacement method to find the volume. Then divide Density = mass / volume.
To find the volume of an irregularly shaped object that would dissolve in water, you can use the water displacement method. Fill a known volume of water in a container, note the initial water level, then submerge the object in the water and measure the new water level. The difference in water levels is the volume of the object.
One way to find the volume of a large irregular shape object is to use the displacement method. Submerge the object in a container of water and measure the volume of water displaced. This volume is equal to the volume of the irregular object.
if it is a solid, use the water displacement method.
You use the displacement formula when you put an object in water and need to find the volume of the object.
If the solid is a regular shape, such as a cylinder or sphere, you can find the appropriate dimensions and use formulas to find the result. If it is of a irregular size, I doubt if there is another method (even if there is, displacement of water would most likely be the simplest method)
Density is calculated by dividing the mass of a substance by its volume. To find the volume, you can measure the dimensions if it is a regular shape, or use water displacement method for irregular shapes. Once you have the mass and volume, divide the mass by the volume to find the density.
The water displacement method is used to find the volume of irregularly shaped objects. This method is not necessary for regularly shaped objects whose volume can be easily calculated using geometric formulas. Irregularly shaped objects do not have a straightforward formula for volume calculation, hence the need for the water displacement method.
