Question: A crystalline solid....
A crystalline solid.
A
Changes abruptly from solid to liquid when heated
B
Has no definite melting point
C
Undergoes deformation of its geometry easily
D
Has an irregular 3-dimensional arrangements
(e) Softens slowly
Answer
Changes abruptly from solid to liquid when heated
Explanation
Solution
In crystalline solid there is perfect arrangement of the constituent particles only at 0K. As the temperature increases the chance that a lattice site may be unoccupied by an ion increases. As the number of defects increases with temperature solid change in liquid.
