Question

Quizplus · Accepted Answer

The mixture of ethylene glycol and water in a coolant utilizes both colligative properties (such as boiling point elevation and freezing point depression) and the boiling point elevation constant of water. Therefore, both choice A and C are correct, making E the best choice. The boiling point depression constant of water (choice D) is not relevant in this scenario as the coolant is designed to prevent overheating, not to lower the boiling point of water.
