Question

Oobservation of boiling point of ethylene glycol and water solution?

Answer 1

Specifically, a mixture of 60% ethylene glycol and 40% water freezes at −45 °C (−49 °F). ... Thus, the use of ethylene glycol not only depresses the freezingpoint, but also elevates the boiling point such that the operating range for the heat-transfer fluid is broadened on both ends of the temperature scale.
