Question

Consider the standard cooling curve of a pure crystalline solid. How many distinct break points (sharp bends indicating the beginning and end of crystallization) are observed in its cooling curve?

Answer: 2

💡 Solution & Explanation

A crystalline solid exhibits two distinct breaks in its cooling curve. The first break point indicates the beginning of crystallization, and the second break indicates the end. During this specific time interval, the temperature remains constant as the energy liberated compensates for the heat loss.
