Amorphous solids turns into glass-like state from rubber-like state, this is called _ ?

Explanation

Option A: Transition refers to a change or conversion from one state or form to another. In the context of amorphous solids turning into glass-like states from rubber-like states, it can be considered as a general term, but it doesn't specifically describe the phenomenon. Option B: Crack transition typically refers to the propagation or growth of cracks in materials, which is not directly related to the transformation of amorphous solids into glass-like states. So, this option is not applicable in this context. Option C: The glass transition is the process in which amorphous materials, such as certain polymers or non-crystalline solids, undergo a reversible transition from a rubbery or viscous state to a glassy or rigid state. It occurs when the temperature of the material is lowered below its glass transition temperature (Tg). At this point, the material becomes more brittle and rigid, with its molecular structure freezing into a disordered, non-crystalline state resembling glass.Option D: This option is not correct because only option C (Glass transition) is applicable in the given context, while options A (Transition) and B (Crack transition) are not accurate descriptions of the specific phenomenon discussed.
