Which principle is used for the measurement of density Solution-diffusion Gibbs Archimedes Newton

The principle used for the measurement of density is Archimedes' principle. Here are the steps:

1. Archimedes' principle states that the upward buoyant force exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces.

2. To measure the density of an object, you first weigh it in air. This gives you its mass.

3. Then, you immerse the object in a fluid (usually water) and weigh it again. This gives you the weight of the fluid displaced by the object.

4. The difference between the weight of the object in air and the weight of the object in the fluid gives you the buoyant force.

5. The density of the object is then calculated by dividing its mass by the volume of the fluid displaced, which is equivalent to the volume of the object.

6. The formula is: Density = Mass / Volume

So, Archimedes' principle is used for the measurement of density.
