The permanent electric dipole moment of K, Rb or Cs atom can not be calculated by using the Boltzmann constant. Pei-Lin You Institute of Quantum Electronics polarization of polar molecule, such as HCl or H2O etc, is a molecule as a whole turned toward the direction of an external field.The molecular electric dipole moments are of the order of magnitude of the electronic charge (1.6×10-19 C) multiplied by the molecular dimensions (10-10 m),or about 10-30 coulomb-meters. If K atom is the polar atom, a temperature dependence of the formχe = B/T should be expected in...Problem 30 Easy Difficulty. The permanent electric dip… 01:37. The dipole moment of the w… 02:32. A diaper moment B is equal to a few times. D and D is equal to be divided by kun. Well, these 6.2 multiply by 10 to the power minus 30.Water molecule dipole moment. Thread starter Useful nucleus. 1D = 0.20822678 e.A. So the result that I get is 2.3 D. While this gas phase geometry of the water molecule has a dipole moment of 1.86D. So you can say that they are part of the given model. Aug 26, 2009. #10.

The permanent electric dipole moment of the water molecule...

Video Explanation. Answer. Dipole moment of water molecule P=6×10−30Cm. External electric field applied E=1.5×104NC−1. Maximum torque τmax =PE=6×10−30×1.5×104=9×10−26 Nm. Answer verified by Toppr.Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from One of the most common examples is the water molecule, made up of one oxygen atom and two hydrogen atoms.Why does water have a dipole moment? Fundamentally, dipolar simply means that a region of the molecule has a center of positive charge and a Such molecules are said to be polar because they possess a permanent dipole moment. A good example is the dipole moment of the water molecule.For the water molecule, the dipole is the first nonzero multipole moment; it represents the polarity of the molecule and has been widely used in describing solvation behavior. A rather wide range of theoretically determined values for the total molecular dipole moment of water in condensed...What is the maximum possible torque on a water molecule in a 3.6×108 N/C electric field?

In an electric field E, the torque applied to a dipole P is given vectorially by the cross-product

P x E

The maximum magnitude of that torque is |P|.|E| (it occurs when P and E are perpendicular):

|P|.|E| = (6.2 e(-30) C.m) . (3.58 e (+8) N/C ) = 2.2196 e(-21) = 2.22 x 10^(-21) N.m

Note that 1 N/C = 1 V/m. So, the electric field mentioned corresponds to

a 358,000 volts difference over a displacement of 1 mm. Just a thought.
