The image below shows a group of wind turbines, which can be used to produce electrical energy. Several transfers of energy must occur to produce this electrical energy. First, an uneven transfer of _ energy to Earth's atmosphere produces wind energy. As the wind rotates the blades of a turbine, _ energy is transferred to the turbine. This transferred energy then turns generators inside the turbine to produce electrical energy.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
