Answer:
The pink substance underwent a phase change because its molecules were held together by weaker attractive forces compared to those of the green substance. The molecules in the pink substance moved rapidly enough to facilitate the phase change. In contrast, the molecules of the green substance experienced stronger attractive forces, meaning the energy supplied to them was insufficient to overcome these forces and prompt a phase change.
Prophylactic administration of diazepam may not prevent the onset of seizures since they result from theophylline usage. Tachycardia and seizures are recognized toxic effects associated with elevated theophylline levels. Due to its narrow safety margin, monitoring theophylline blood levels is essential to mitigate these toxicities. Additionally, caffeine exacerbates the toxicity associated with theophylline.
