Calculate the melting temperature of Br2 under a pressure of 2 MPa, assuming the density of solid bromine is 4.050 g/cm3 , and that of liquid bromine is 3.102 g/cm3 , both assumed to be independent of temperature and pressure.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
