Question

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

Answer 1

A crystalline solid : (a) changes abruptly from solid to liquid when heated.

- Crystalline solids have a definite and very sharp melting point.

- They have a regular and fixed 3-D arrangement of particles.

- They do not undergo deformation of its geometry even on heating.

- They do not soften over a range of temperature.

- In fact on heating, the crystalline solids changes abruptly from solid to liquid when they reach their melting points.
