Particles of quartz are packed by:(i) Electrical attraction forces (ii) Vander Waal's forces (iii) Covalent bond forces (iv) Strong electrostatic force of attraction Answer: (iii)
In a liquid a solid substance a molecule present within the bulk of the substance is being attracted infirmly from all sides by the neighbouring molecules. Hence there is no bet force acting on the molecule or there are no unbalanced forces of the molecule. On the oth
