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 ...
Consequently, at a given temperature and ethanol concentration, the freezing process will reach an equilibrium at a specific ratio of water ice and enriched ethanol solution with a specific ethanol concentration. The temperatures and mixing ratios of these phase equilibria can be read from the phase diagram of ethanol and water. The maximum ...
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
While your pipes can be at risk of freezing any time temperatures drop below 32 degrees, it is most common for them to start freezing once temperatures dip below 20 degrees.
Freezing temperatures from a harsh arctic blast are expected to affect nearly 300 million Americans across most of the continental U.S. in the coming days, according to the National Weather Service.
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 − ...
