Question

Explain an aqueous solution of urea boils above 100°C but freezes below 0°C.​

Answer 1

An aqueous solution containing urea found to have boiling point more than the normal boiling point of water (373.13 K). When the same solution was cooled, it was found that its freezing point is less than the normal freezing point of watre (273.13K). ... In other words, the boiling point of the solution gets raise.
