       Hope someone check and comment whether the list of definitions
       are acceptable and identify misconceptions in each
       answers.Thanks. Below are the list of answers from different
       people.
       A Physical change is:
       a) A change that can be seen by naked eyes.
       b) A Change in shape, size, weight, structure and substance
       state (solid, liquid and gas)
       c)The change that affects the arrangement of particles
       d) when the state of an element or a compound changed
       e) A reaction which is observed
       f) A change in colour, states,strength and arrangement
       g) The change of appearance of a substances
       A chemical change is:
       a) changes that occur during the reaction
       b)changes that occur during the reaction between two substances
       or more
       c)A reaction which is not visible
       d) when the compound has completely change
       f)The change in reaction where the particles actually react with
       another
       g) when the atoms in the structure perform chemical changes
       between atoms and molecules
       h) A change in molecular formula
