Mixing solvents creates cooling baths with variable freezing points. Temperatures between approximately −78 °C and −17 °C can be maintained by placing coolant into a mixture of ethylene glycol and ethanol, while mixtures of methanol and water span the −128 °C to 0 °C temperature range. Dry ice sublimes at −78 °C, while liquid nitrogen is used for colder baths. As water or ethylene glycol freeze out of the mixture, the concentration of ethanol/methanol incr… Web26 Dec 2005 · The temperature will have decreased.
