The "speed" of the movement of the gas molecules increases and the kinetic energy increases as the temperature increases. In Kinetic Molecular Theory for an Ideal Gas there is no "energy of attraction" between gas molecules. In a real gas in the real world and not an abstract theory there is an energy of attraction. The energy of attraction decreases as the temperature increases. This is evaporation. However be careful when talking about energy of attraction. At a quantum level it can be considered that this "energy" does not change, however it is overwhelmed or overtaken by the kinetic energy. A good place to start is with Boyles Law - http://en.wikipedia.org/wiki/Boyle's_law#Relation_to_kinetic_theory_and_ideal_gases
