Question

Could you give me a suitable example for application of Archimedes' Principle?

Answer 1

1) A ship floats on the surface of the sea because the volume of water displaced by the ship is enough to have a weight equal to the weight of the ship.

2) We can check whether milk has been diluted with water or not by using a lactometer. Here also buoyancy principal is used. Diluted milk is lighter and hence lactometer sinks more in diluted milk.

3) Similarly a saccharometer is used for determining the amount of sugar in a solution. It is used primarily by winemakers and brewers. It also works on the principle of buoyancy. A solution with a higher sugar content is denser, causing the bulb to float higher. Less sugar results in a lower density and a lower floating bulb.
