Explain how you would determine the volume of a powdered solid, a liquid, and a rock

Volume may be defined as the quantity of the three dimensional space that is enclosed by a particular closed surface. The S.I. unit of the volume is cubic meter.

The volume exist for solid, liquid and gases. The volume of the object can be calculated by the formula:

Density = mass/ volume

Volume = Density/ mass.

The volume of any object can be measured by diving the density of that object with respect to its mass.

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.

the answer is b & c i believe : )
