Principio de Arquímedes - Experimento

Understanding Archimedes' Principle Through an Experiment

Introduction to the Experiment

• The experiment aims to demonstrate Archimedes' principle, which states that any object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced.

• Materials needed for the experiment include three transparent glasses filled with water at the same level and three eggs.

Step-by-Step Procedure

First Case: Egg Sinking

• In the first glass, an egg is submerged. It sinks completely because its weight is greater than the buoyant force exerted by the water.

Second Case: Egg Floating Midway

• In the second glass, salt is added to increase water density. When a second egg is placed in this solution, it floats midway.

• This occurs due to two opposing forces acting on the egg: gravity pulling it down and buoyancy pushing it up. Here, these forces are balanced.

Third Case: Egg Floating on Top

• For the third case, significantly more salt is added compared to the second glass. The third egg nearly floats on top of the solution.

• This demonstrates that when enough salt increases water density, buoyant force surpasses gravitational pull on the egg, allowing it to float almost entirely.
