Assertion: Amorphous solids do not have a definite melting point.

Reasoning: In amorphous solids, the constituent particles are arranged in a disordered and random manner, and therefore, there is no well-defined pattern of melting. The heat energy required to break the intermolecular forces and change the solid into a liquid is gradually absorbed over a range of temperatures, leading to a broad range of melting points.

 

Option: 1

Both the assertion and reasoning are true, and the reasoning is the correct explanation for the assertion.

 


Option: 2

Both the assertion and reasoning are true, but the reasoning is not the correct explanation for the assertion.


Option: 3

Option: 4

The assertion is false, but the reasoning is true.


Answers (1)
