From the experiment found that the factors that affect to substance which was cool down is
concentrations and crystal structures.the tendency of ccurrence of crystal structures is according to Vegard’s Law
and also found that the occurrence of phase of sample A is during cool temperature down, liquid phase would be transform
to solid phase in term of BaZrO3(II)- A. For sample C , BaZrO3(II)- C in term of solid phase would expand but it had no phase occurred.
For differential of concentration found if use HNO3 to be solvent, then the concentration of Ba would be decrease due to Ba react to HNO3
then evaporated to surrounding.For differential of concentration found if use H2SO4 to be solvent found that the concentration of
Ba would be constant because it occured in term of solid when Ba react to H2SO4.
