Why Mercury is spherical in shape liquid?
The reason mercury droplets are spherical is because they do easily wet other surfaces. For this reason, mercury forms spheres, which have the smallest possible ration of surface area to volume.
Why does water form spherical drops on some surfaces?
Water forms spherical drops on hydrophobic surfaces because the molecules have a tendency to minimize contact with the surface due to surface tension. This shape reduces the surface area in contact with the surface, allowing the water droplet to bead up into a more stable and energetically favorable shape.
Why does liquid bead into tiny spheres when splashed onto extremely hot surfaces?
When a surface is far above the liquid's boiling point and the liquid is dropped onto it, the part of the liquid which first contacts the surface flashes into vapor. The vapor forms a layer under the liquid. The liquid is "shattered" into drops by the force of the suddenly expanding and escaping vapor and by the liquid's surface tension. The vapor is a poor heat conductor which then protects the drops riding on top of it. This is called the "Leidenfrost effect".
The organism called volvox forms spherical what?
The organism called Volvox forms spherical colonies made up of many individual cells called zooids. These colonies can range in size from a few hundred to thousands of cells and are held together by a gelatinous matrix. Each zooid has two flagella that help the colony move through the water.
Why are rain drops spherical?
Raindrops are spherical due to surface tension. Surface tension causes water molecules to be attracted to each other, pulling them into a shape with the smallest surface area, which is a sphere. This shape allows raindrops to travel through the air more efficiently.
What is it called when a solid forms from a liquid mixture?
When a solid forms from a liquid mixture, that is a precipitate, unless the liquid is in the process of freezing, in which case it is a phase change.
When drops of water collect on surfaces near the ground due to cooling its called?
dew
When water vapor condenses directly onto a surface such a grass or a windowthe condensed drops of water are called?
The condensed drops of water are called dew on grass and condensation on window surfaces. Dew forms due to the cooling of the surface below the dew point temperature causing water vapor to condense into liquid water droplets.
When a gas touches a cold surface and the temperature of the gas drops it forms what?
When a gas touches a cold surface and its temperature drops, it can form condensation, which is the process of changing from a gaseous state to a liquid state.
Why liquids drops are spherical?
If the drop is small enough, it is a perfect sphere. A sphere is the geometrical shape thathas the smallest surface area for its volume. The drop takes this shape because watermolecules tend to stick to each other. So, when not confined by a container, and withnothing around it to distort its shape, a very tiny water drop is perfectly round like aball because the water molecules are pulling inward toward each other.
What is the three forms of matter called?
They are solid , liquid , and gas.
What the is crescent shaped surface of liquid that forms in pipettes and graduated?
The crescent shaped surface of liquid that forms in pipettes and graduated cylinders is called a meniscus.
