This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum surface area is "spherical shape".
chemistry in action - Detergents A result of high dissolving power, the logically happening water all time consists of dissolved matters, majorly ionic substances. Hard water h
What is Vapor Density? Vapour density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of
production of pure spectrum
A 12 Volt battery is associated across a parallel combination of two capacitors C1 and C2. The capacitance of C2 is double that of C2.
Q. If 6.25 X 10 18 electrons flow through a given cross-section in unit time, find the current. Solution: Current I = q / t = ne / t = (6.25 X 10 18X 1.6 X 10 -19) / 1 = 1 A
Q. Will a DC motor really produce voltage if it is spun in reverse? Answer:- It will produce voltage if you spin it forwards too. The merely difference between a DC motor
(1) CAPACITANCE: The value of capacitance depends upon the area of conducting plates, thickness of dielectric material and its permittivity. The frequency of operation
Q. During lightning, it is safer to sit inside car than in an open ground. Why? The metal body of the car offers electrostatic shielding where the electric field is zero. Thro
The molecules of diatomic and linear polyatomic gases are made up of two atoms joined rigidly to one another by a bond. Such a particle cannot only move as a entire but can also ro
Capacitors in series: When three capacitors are connected in series. If one electron moves from the negative terminal of the cell to the right hand plate of C 3 , and one elec
The force of attraction between the molecules of water is higher.
Because of surface tension, every thing in the universe wants to achieve stability,they do that by lowereing their energy.which in this case is the surface energy.a sphere offers lowest surface area yet a very large volume
