Why the shape of liquid is spherical?
In case of liquids attractive force of surface tension causes drops to take spherical shape. Because the sphere has the smallest surface area and surface tension tends to minimize the surface area. Due to this reason the shape of liquid drop is spherical.
Why does mercury bead up?
Question: Why does mercury bead up into spheres so readily? Mercury has extremely high cohesion and surface tension due to its strong metallic bondsb. Mercury has extremely high cohesion and surface tension due to its strong dispersion forcesc. Since mercury is a liquid, it is not able to make metallic bonds.
Why liquid drops and bubbles are spherical in shape?
The attractive force of surface tension causes the bubbles to take spherical shape. Because a sphere has the smallest surface area compared to other shapes with the same volume occupied, so it enables the particles to pack together close enough to achieve the tightest possible grouping than any other shape.
Why is liquid drop round?
Raindrops take up the spherical shape due to the surface tension of water which is caused due to the tendency of water molecules to stick together. The spherical shape is having the least possible surface area due to which it can resist any of the external force in the atmosphere.
Why are water droplets spherical quizlet?
Why are water droplets spherical? They are spherical because of the surface tension caused by the attractive forces. Intermolecular forces pull water inward to form a sphere. The sphere minimizes the surface area to volume ratio, thereby minimizing the number of molecules at the surface.
Is mercury attracted to itself?
The surface tension produced by cohesion makes it possible for light objects to float on water without sinking (e.g., water striders walking on water). Another cohesive substance is mercury. Mercury atoms are strongly attracted to each other; they bead together on surfaces. Mercury sticks to itself when it flows.
Why does water wet glass and mercury doesn t?
When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. Mercury does not wet glass – the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.
Why are drops and bubbles spherical Class 11?
A sphere has the minimum surface area of all shapes that enclose a given volume. So the surface tension tends to minimize the surface area and to compensate it the molecules group together to form the best possible shape for the situation, which is a sphere. Thus the bubbles are spherical in shape.
Are drops and bubbles spherical?
Therefore, drops and bubbles acquire spherical shape in order to have the minimum surface area.
What liquid has the lowest surface tension?
Hexane, C6H14, has the lowest surface tension of all the liquids given here. Hexane is a non-polar molecule, the only intermolecular forces acting between hexane molecules in the liquid will be the weakest of all the intermolecular forces, London forces (also known as dispersion forces).
Are water droplets spherical?
KnowHOW team explains: Water drops, or, for that matter, the drops of any other liquid, are spherical in shape due to a phenomenon called surface tension. Since a sphere has got the minimum surface-to-volume ratio, falling liquid drops are always spherical in shape.
What is the word that means water is attracted to itself?
The attraction between individual water molecules creates a bond known as a hydrogen bond. Thus, the exact number of hydrogen bonds formed per molecule varies. Cohesion. Molecules of pure substances are attracted to themselves. This sticking together of like substances is called cohesion.
