Ответ:

1 - лед

2 - стекло

Стекло (только ближний порядок, нет дальнего порядка (ближе к жидкостям)) не имеет точки плавления как таковой (она размыта), потому мы видим на графике постоянное увеличение температуры. Для льда же мы видим на графике фазовый переход первого рода - плавление (переход из твердого состояния в жидкое). При плавлении кристаллического тела (льда) теплота, подаваемая веществу, используется на разрушение кристаллической структуры и преодоление сил взаимодействия между его молекулами, т.е. энергия, которая подается для плавления, не повышает температуру, а используется на разрушение кристаллической структуры.
