Very small droplets of Hg is an almost spherical.
Why?
Demonstrate (i.e., with a proof instead of a specific example) that fusing two identical spherical droplets of some dispersed liquid into a single new spherical droplet reduces the collective surface area by 21%. Why is this fact important for emulsion stability?
In the famous Millikan oil-drop experiment, tiny spherical droplets of oil are sprayed into a uniform vertical electric field. The drops get a very small charge (just a few electrons) due to friction with the atomizer as they are sprayed. The field is adjusted until the drop (which is viewed through a small telescope) is just balanced against gravity and therefore remains stationary. Using the measured value of the electric field, we can calculate the charge on the drop and...
When a spherical droplet of liquid is sheared into much finer droplets, which of the following statement is correct for the final droplets? please explain your answer a. The sum of the radii of all the droplets will be equal to the radius of the initial droplet b. The mass of a single final droplet is same as that the initial droplet c. The sum of the volume of all the final droplets is same as that of the initial...

Question Fog may be modeled, as a mixture of small spherical water droplets in air. To a first approximation, the Maxwell-Garnett mixture rule for the effective permittivity of the water-air mixture takes the form: eff.oee Wheren the low frequency and optical permittivity of the fog. The relaxation time for the susceptibility of the fog is Feff and is related to the resonance frequency as f-y2 eff ·The parameters of the mixture are defined by -cair Soo,e ir E +2air-e-Eair refy...
Why a small crystal of metal is often facet instead of spherical
Aerosols form when a liquid is dispersed in air as small suspended droplets. Aerosols are (A) gaseous solutions. (B) heterogeneous mixtures of liquid water and gaseous air. (C) compounds. (D) homogeneous mixtures of gases comprising air. (E) heterogeneous mixtures of gases comprising air.
A uniformly charged spherical droplet of mercury has electric potential Vbig throughout the droplet. The droplet then breaks into n identical spherical droplets, each of which has electric potential Vsmall throughout its volume. The n small droplets are far enough apart from one another that they do not interact significantly. Find Vbig/Vsmall, the ratio of Vbig, the electric potential throughout the initial drop, to Vsmall, the electric potential throughout one of the smaller drops. The ratio should be dimensionless and...
Select the statements that explain why very small and very large populations experience slow population growth under the logistic growth model. 1- Small populations have fewer individuals capable of producing offspring. 2- Limited resources are shared among many individuals in very large populations. 3- The intrinsic growth rate is higher when populations contain many individuals. 4- The carrying capacity is larger for populations that contain very few individuals.
In regular alcohol consumers, lipids get accumulated in the liver and are stored as small droplets in liver cells and this condition is known as _____. Multiple Choice fatty liver liver cirrhosis Wernicke-Korsakoff syndrome hemochromatosis
