The hairs of the shaving brush stick together when taken out of water due to surface tension. Water molecules at the surface of the hairs attract each other, causing them to cling together. This phenomenon is a result of cohesive ...

When kerosene oil is added to stagnant water, mosquitoes reduce because it interferes with the breathing of the larvae. The thin layer of oil formed on the water’s surface blocks the larvae’s access to air, effectively suffocating them. This disrupts ...
The shape of a raindrop becomes spherical primarily due to surface tension. Surface tension causes water molecules at the surface to contract, pulling the raindrop into the shape with the least surface area, which is a sphere. This phenomenon occurs ...
The principle of purification by soap relies on surface tension. Soap molecules disrupt surface tension, allowing them to surround and lift away dirt and oil from surfaces. This process enables effective cleaning by ensuring that contaminants are dispersed and washed ...
Oil spreads on the surface of water because the surface tension of oil is less than that of water. This causes oil molecules to spread out more easily, forming a thin layer on the water’s surface. This phenomenon occurs due ...
The great scientist Archimedes belonged to Greece. He was born in Syracuse, a Greek colony in Sicily, around 287 BC. Archimedes made significant contributions to mathematics, physics, engineering, and astronomy, and is considered one of the greatest mathematicians of all ...
Any boat will sink if it displaces water equal to its weight. According to Archimedes’ principle, the buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object. Therefore, ...
The reason for a piece of iron not floating on the surface of water is that the weight of water displaced by iron is less than the weight of iron. According to Archimedes’ principle, for an object to float, the ...
The amount of buoyancy obtained by a solid partially or completely immersed in a liquid depends on the amount of liquid displaced by the solid. This is according to Archimedes’ principle, which states that the buoyant force experienced by an ...
Scientists related to buoyancy are Archimedes. Archimedes formulated the principle of buoyancy, also known as Archimedes’ principle, which explains the upward buoyant force exerted on an object immersed in a fluid. This principle is fundamental in understanding the behavior of ...
