Engineer Roland Krevitt, left, of Scotts Valley, and inventor and metallurgist Bob Wallace, 93, have reverse engineered an Epi-Pen to estimate the cost to make a two-pack of the lifesaving auto-injector that retails for more than $700. Their verdict: $8.02. (Patrick Tehan/Bay Area News Group)
The freezing point of ethanol or ethyl alcohol (C2H6O) is around â114 Â°C; â173 Â°F; 159 K. The freezing point of methanol or methyl alcohol (CH3OH) is around â97.6 Â°C; â143.7 Â°F; 175.6 K. You'll find slightly different values for the freezing points depending on the source because the freezing point is affected by atmospheric pressure.
Denatured fuel ethanolâs. specific gravity is 0.79, which indicates it is lighter than water and it has an auto-ignition. temperature of 689Â°F and a boiling point of 165-175Â°F. Ethanol is less toxic than gasoline or methanol.
