   NO!!!   
      
   Water is not a liquid per se.   
      
   Instead water occurs in three different states, from which only one is   
   liquid.   
      
      
   Energy is also something else than mass, because the term 'energy'   
   denotes a quantity in physics and this has a different meaning than 'mass'.   
      
   Mass is actually a measure for resistance against acceleration and   
   measured in kg.   
      
   Energy is derived from the quantity work, which is defined as   
   W=force*distance.   
      
   The units are Newtonmeter or Joule.   
      
   The quantity you erroneously call 'mass' is not measured in kg but in mol.   
      
   What you actually wanted to say, that is: matter is actually immaterial   
   and a form of energy.   
      
   BUT: 'the amount of matter' is not measured in kg but in mol.
