In order to determine the amount of liquid a spherical tank will hold would you need to use volume or surface area?
One is the liquid's surface tension. A drop of water will be quite spherical because is has strong surface tension, meaning the edges of the droplet are drawn into the centre. Another factor could be the speed with which the drop falls, as the air particles will have to be pushed apart quicker, making the droplet more streamlines, therefore less spherical.
Liquids tend to form spherical droplets because of surface tension. There is energy associated with the surface tension, and since a sphere has the minimum surface to volume ratio, it has the minimum surface tension related energy for a given amount of liquid. (It is a general principle in physics that things tend toward a minimum energy state.)
A force that acts on the particles at the surface of a liquid and causes some liquids to form spherical drops is?
Prescriptions for corrective vision for nearsighted persons always include a spherical part. If the person has astigmatism along with nearsightedness, the prescription will also include a cylindrical part. A small amount of a liquid with a high surface tension in a near vacuum in space with no disturbing gravitational field will assume a spherical form, because that minimizes the area of surface for any particular volume.
Usually, a liquid does not have a predetermined or definite shape. It will take on the shape of the container it is in or surface it is on. The only extenuating circumstance is during free-fall, or where there is negligible or no gravity - it will be become almost spherical, held together by surface tension.
Spherical tanks distribute the vapor pressure from within the tank equally to the inner surface of the tank. If one were to make a tank a cube or a cylinder, you would have to use a lot more metal to create a tank strong enough to hold the same amount of boiling liquid. Dams are built in a curved manner (check images of the Hoover Dam) along the same principles- to distribute pressure evenly to…
Short answer: Water beads form on a surface when the cohesion of the water molecules with each other is much greater than the adhesion of the water to the surface. Water cohesion results in water having high surface tension and hence a strong tendency to form spherical droplets. Water adhesion to waxy or oily materials is small. The result is a tendency to form water beads. This phenomena, or the lack there of, is called…
Actually yes it does. The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor. Evaporation is a phenomenon in which molecules located near the liquids edge, not contained by enough liquid pressure escape into the surroundings as a vapor. So if I have a small surface area such as a pot with the same amount…
