Cooling curves for amorophous and crystalline substances represented as follows

Collect statement regards (A) and (B) graphs

Options

A. Graph (A) represents amorophous and Graph (B) represents crystal line substances
B. Graph(A) represents crystalline and graph (B) represents amorophous substances
C. In graph(B) , two points a , b represents beginning and end of the process of crystallation .
D. In graph(B) , Temperature remains constant from `a rarr b` , because as the process of crystallisation is accompanied by some absorbation of energy , which campensates for the loss of heat and causes the temperature to remains constant .

Answer

A, C, D
