WORLD HISTORY

Detailed explanation-1: -Archimedes thought long and hard but could not find a method for proving that the crown was not solid gold. Soon after, he filled a bathtub and noticed that water spilled over the edge as he got in and he realized that the water displaced by his body was equal to the weight of his body.

Detailed explanation-2: -How compact, or closely packed, an object is determines how much water it will displace and, therefore, whether it will float or sink. This compactness is referred to as density. Density is mass per unit volume. If an object is more compact, or denser, than water, it will sink in water.

Detailed explanation-3: -Archimedes’ principle states that: “The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid”.

Detailed explanation-4: -In simple words, Archimedes’ principle states that, when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body(s).

Detailed explanation-5: -A submerged object displaces a volume of liquid equal to the volume of the object. One milliliter (1 mL) of water has a volume of 1 cubic centimeter (1cm3). Different atoms have different sizes and masses.
