Do Physicists Drink? - Debating the Risks of Alcohol - Physics …
2010年1月1日 · Kaku answered simply by saying that Physicists do no drink, and celebrate in different ways. Anywho, all of this leads me to believe that there are two sides to the matter of drinking alcohol. Either people drink alcohol and do not care of the damage it causes to their brain, or people do not drink in fear of that damage being caused.
Why is ethanol the only drinkable alcohol? - Physics Forums
2003年12月22日 · Ethanol is considered the only drinkable alcohol because it is the only type of alcohol that can be safely consumed in moderate amounts without causing severe harm or intoxication. Other types of alcohols, such as methanol and isopropyl alcohol, are toxic and can cause serious health problems if ingested. 2.
What Happens to Alcohol When it Evaporates? - Physics Forums
2014年9月5日 · Alcohol evaporates due to the kinetic energy of its molecules. The higher the temperature, the more kinetic energy the molecules possess, leading to increased evaporation rates. Additionally, alcohol molecules are relatively small and have weaker intermolecular forces compared to water, making them more prone to evaporation.

Pressure on manometer with different fluids - Physics Forums
2013年7月8日 · The pressure measured by a manometer will vary depending on the type of fluid used. This is because different fluids have different densities and weights, which affects the height of the fluid column. For example, a manometer using water will measure a lower pressure than one using mercury, as water is less dense and creates a shorter column.
How did Native people purify water - Physics Forums
2009年2月24日 · Most people drank 'small beer' a weak low alcohol beer from the second boiling of the mash - although boiling purifies the water it didn't have enough alcholo content to keep it pure.
