Explanation:

1) When phosphoric acid reacts with calcium hydroxide neutralization reaction takes place in which calcium phosphate is formed along with formation of water.

The balanced chemical equation is give as:

$2H_3PO_4+3Ca(OH)_2\rightarrow Ca_3(PO_4)_2+6H_2O$

2) When calcium oxide acid reacts with phosphorus pentoxide addition reaction takes place in which calcium phosphate is formed.

The balanced chemical equation is give as:

$3CaO+P_2O_5\rightarrow Ca_3(PO_4)_2$

The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.
