Chemistry is a physical science that deals with the composition, structure and properties of substances and the reactions they undergo anything that does not work is physics in the definitions about terms likematerials, substances are used the term matter could replace both of these words. Enthalpy of atomization is the energy released when molecules break into their atoms jgi/jamie grill / getty images if pressure is held constant, enthalpy change equals the change in the internal energy of a system so, enthalpy of atomization equals the sum of the enthalpies of fusion and vaporization.
During electrothermal atomization, a sample goes through three phases to achieve atomization however, electrothermal atomizers have disadvantages including slow measurement time because of the heating and cooling required of the system and a limited analytical range.
