principles of reactivity: energy and chemical reactions
... The more __________________________a substance has, the greater the temperature of its atoms and molecules. The total thermal energy in an object is the sum of its individual energies of all of the molecules. For any given substance, its thermal energy depends not only on its composition, but ...
