Question

Which of the following are properties of an amorphous solid?

• A. It has short range order
• B. It is anisotropic in nature
• C. The melting point is not fixed.
• D. They are made up of small crystals which have regular shape and arrangement of particles

Answer 1

Answer: (A), (C)

The correct options are
A

It has short range order

C

The melting point is not fixed.

Here we are talking about – Amorphous solids.

The name itself suggests a – morphe which means form, so amorphous means without form.

In amorphous solids the particles are arranged in irregular manner.

So, option (d) is wrong.

$\to$ This will lead to a range of melting point not a fixed melting point.

$\to$ There is no long range order and the arrangement is irregular in all directions, therefore it will be isotropic in nature which means they will show similar physical properties along all directions.

Therefore, the correct options are (a) and (c).
