2. Environment

   • Energy
     • Doesn't occupy space & no mass
   • Matter
     • Occupy space & have a mass
     • According to the physical nature
       • Solid
       • Liquid
       • Gas
     • According to the chemical nature
       • Mixtures
         • Homogeneous
         • Heterogeneous
       • Pure Substances
         • Compunds
         • Elements
