Weband causing water to have high surface tension. 6. At water’s surface, its molecules are only attracted to the water molecules below and to the sides of them, as there is only air above these molecules. So, the surface molecules of a body of water are pulled down, creating a much more stable, stronger arrangement. • Inquiry Discussion 2 WebThe Path to Power читать онлайн.
