How can I get more energy?

How can molecule like H2 molecule which has two electrons in the bonding orbital can get kinetic energy? What are the difference way it can get kinetic energy?

  • Answer:

    The simplest way to increase the kinectic energy of a molecule is to increase the temperature or the pressure of the system. The temperature increases the vibrational energy of the molecule (in H2, there is symmetric and antisymmetric stretching of the nucleous). Higher pressure allow the increase of the number of shocks among molecules. If one consider one of the most known equations in physical chemistry E=1/2.Kb.T (Kb is the boltzmann constant and T the absolute temperature) one can see a linear behavior of the energy with temperature.
