CHEMISTRY

1. Defination

   • Chemistry is the study of the composition, structure, properties, and reactions or transformations, and behavior of matter and the changes it undergoes.

2. MATTER

   • Defination
     • Matter is the physical material of the universe; it is anything occupying space and having mass.
   • characterized or classified
     • Its physical state (gas, liquid, or solid)
       • Shape
         • Solid
           • has a fixed (definite) shape
         • Liquid
           • has no fixed shape (take the shape of the container)
         • Gas
           • has no fixed shape (take the shape of the container)
       • Volume
         • Solid
           • has a fixed (definite) volume
         • Liquid
           • has a fixed (definite) volume
         • Gas
           • has no fixed volume (Fills the volume of the container)
       • Arrangement of Particles
         • Solid
           • Fixed
         • Liquid
           • very close Random
         • Gas
           • far apart
       • Interaction between Particles
       • Movement of Particles
       • Compression
         • Solid
           • Not able
         • Liquid
         • Gas
     • Its composition (whether it is an element, a compound, or a mixture).

3. Importants

   • Chemistry is central to a fundamental understanding of governing principles in many science-related fields (biology, engineering, pharmacy, agriculture, geology, or some other field).
