A crystalline solid is a solid material whose atoms are arranged in a highly ordered, repeating three-dimensional pattern.
[Kerala CET (Med.) 2003]
Options:
A) Changes abruptly from solid to liquid when heated
B) Has no definite melting point
C) Undergoes easy deformation of its geometry
D) Has an irregular three-dimensional arrangement
E) Softens slowly
Show Answer
Answer:
Correct Answer: A
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 becomes liquid.
