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.
Twenty minutes later, the freezer was starting to have a genuine deliciousing effect. I measured the bottles. The freezer beer was now down to 48.5Â°F (9Â°C), just a shade warmer than the ice bath beer (47.5Â°F (8.6Â°C) The ice water was almost at its limit when it came to cooling power. It was hard to imagine the beer getting any closer to freezing temperature (32Â°F 0Â°C) when the ice water itself wasn't there yet.
