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.
Both the assertion and reasoning are true, and the reasoning is the correct explanation for the assertion.
Both the assertion and reasoning are true, but the reasoning is not the correct explanation for the assertion.
The assertion is true, but the reasoning is false.
The assertion is false, but the reasoning is true.
a) Both the assertion and reasoning are true, and the reasoning is the correct explanation for the assertion.
Amorphous solids do not have a well-defined melting point, unlike crystalline solids, due to their disordered structure.
