The physical limitation of the ability of a thermometer to measure low temperature is the freezing point of the liquid used. Ethanol freezes at −114.9 °C (−174.82 °F). If an alcohol thermometer utilizes a combination of ethanol, toluene, and pentane, its lower temperature range may be extended to measure temperatures down to as low as − ...
Ethanol-72 Note: without the addition of ethylene glycol, temp is -78 °C. Dry ice: Trichloroethylene-73 Dry ice: Isopropyl alcohol-77 Liquid N 2: Butyl acetate-77 Dry ice: Acetone-78 Liquid N 2: Isoamyl acetate-79 Dry ice: Sulfur dioxide-82 Liquid N 2: Ethyl Acetate-84 Liquid N 2: n-Butanol-89 Liquid N 2: Hexane-94 Liquid N 2: Acetone-94 ...
The temperatures and mixing ratios of these phase equilibria can be read from the phase diagram of ethanol and water. The maximum enrichment of ethanol in the liquid phase is reached at the eutectic point of ethanol and water, approximately 92.4 weight-% ethanol at -123 °C. [3] The best-known freeze-distilled beverages are applejack and ice ...
Grab a bottle or can of room-temperature soda and start shaking it violently. You really want to work those biceps here. Set the bottle in a freezer for three hours and 15 minutes.
A winter storm emerging from the Rockies is forecast to bring rain, snow and ice to a large part of the U.S., the National Weather Service said Friday, bringing below freezing temperatures with it ...
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, [1] while mixtures of methanol and water span the −128 °C to 0 °C temperature range.
