Question

Background: The buoyant force is described by Archimedes principle as: an object, when placed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. The principle applies to an object either entirely or partially submerged in the fluid. The magnitude of the buoyant force depends only on the weight of the displaced fluid, and not on the objects weight.

a.) How will you measure the volume of the solid objects in this experiment?

b.) Explain how the hydrometer measures a liquid

Explanation / Answer

The volume of the liquid displaced will be the same as the same as the volume of the object so to measure the volume you completly sumberge the object and weight the displaced water. you divide the the weight of the dispalced water by desnity water to get the volume of the water _which will give the volume of the object

b.hydrometer works in the Archimedes principle . you put the hydrometer in the fluid . when the fluid has higher densiity it flots higher when the fluid has lower density it goes deeper .

c. Air bubles occupy volume inside the water. so in a sense they increase the volume of the liquid they decrease the density
