ABSTRACT
Molecules in a gas are capable of inde Consider a diatomic gas molecule:
(a) the molecule itself can travel as a whole from one place to another
(b) the molecule can spin around on its axis
(c)
These kinetic energy terms repre significance for the interpretation substance. Changes in internal ener physically as changes in temperature
The total energy of the molecule also contains some potential energy components. Firstly, there are intermolecular forces (such as van der Waals forces) that lead to the formation
f li id d h d b do qu s, an y rogen on s. Secondly, there is the
potential energy associated with the chemical bond between the atoms of the molecule, the bond energy.
