Salt is mixed with water and stirred. Is this a physical or chemical change? Why?
bubbles formed
It melts into water
It is physical because it is easily reversible.
A chemical change may create heat and expansion
rusting of metal parts
Chemical change
chemical changes use the same set of steps and procedures
the egg has new physical properties
