Hamaker Coefficient using Van der Waals Forces between Objects Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hamaker Coefficient = (-Van der Waals force*(Radius of Spherical Body 1+Radius of Spherical Body 2)*6*(Distance Between Surfaces^2))/(Radius of Spherical Body 1*Radius of Spherical Body 2)
A = (-F_VWaals*(R₁+R₂)*6*(r^2))/(R₁*R₂)
This formula uses 5 Variables

Variables Used

Hamaker Coefficient - (Measured in Joule) - Hamaker coefficient A can be defined for a Van der Waals body–body interaction.
Van der Waals force - (Measured in Newton) - Van der Waals force is a general term used to define the attraction of intermolecular forces between molecules.
Radius of Spherical Body 1 - (Measured in Meter) - Radius of Spherical Body 1 represented as R1.
Radius of Spherical Body 2 - (Measured in Meter) - Radius of Spherical Body 2 represented as R1.
Distance Between Surfaces - (Measured in Meter) - Distance between surfaces is the length of the line segment between the 2 surfaces.

STEP 1: Convert Input(s) to Base Unit

Van der Waals force: 110 Newton --> 110 Newton No Conversion Required
Radius of Spherical Body 1: 12 Angstrom --> 1.2E-09 Meter (Check conversion here)
Radius of Spherical Body 2: 15 Angstrom --> 1.5E-09 Meter (Check conversion here)
Distance Between Surfaces: 10 Angstrom --> 1E-09 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = (-F_VWaals*(R₁+R₂)*6*(r^2))/(R₁*R₂) --> (-110*(1.2E-09+1.5E-09)*6*(1E-09^2))/(1.2E-09*1.5E-09)

Evaluating ... ...

A = -9.9E-07

STEP 3: Convert Result to Output's Unit

-9.9E-07 Joule --> No Conversion Required

FINAL ANSWER

-9.9E-07 ≈ -9.9E-7 Joule <-- Hamaker Coefficient

Hamaker Coefficient using Van der Waals Forces between Objects Formula

What are main characteristics of Van der Waals forces?

1) They are weaker than normal covalent and ionic bonds.
2) Van der Waals forces are additive and cannot be saturated.
3) They have no directional characteristic.
4) They are all short-range forces and hence only interactions between the nearest particles need to be considered (instead of all the particles). Van der Waals attraction is greater if the molecules are closer.
5) Van der Waals forces are independent of temperature except for dipole – dipole interactions.
