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.
Is it safe to drink lab ethanol? - Physics Forums
2004年10月22日 — 11. 0. You should never drink lab grade ethanol. There are two main reasons one of which is technical and the other is so-called administrative... Technical is, you cannot have %100 grade ethanol to use in the lab. The major impurity methanol exhibits a azeotrope with the ethanol that is impossible to separate.
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.
Ethanol (Alcohol) 75% and isopropyl alcohol (75%) - any difference?
2021年11月22日 — Both ethanol and isopropyl alcohol are types of alcohol that have a concentration of 75%, meaning that 75% of the solution is made up of alcohol and the remaining 25% is water. The main difference between the two is the type of alcohol molecule they contain. Ethanol, also known as ethyl alcohol, has a two-carbon chain, while isopropyl alcohol ...
Can Isopropyl Alcohol Be Used as Fuel for Rocket Engines?
2016年1月7日 — An isopropyl rocket engine is a type of rocket engine that uses isopropyl alcohol as its fuel source. Isopropyl alcohol, also known as rubbing alcohol, is a colorless and flammable liquid that is commonly used as a disinfectant.

2012年6月23日 — American pioneers relied on various sources to obtain drinking water, including: Rivers and Streams: Pioneers often settled near rivers and streams, which provided a natural source of freshwater. They would collect water directly from these sources. Wells: Many pioneers dug wells to access groundwater.
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. Hence the famous gravestone: Here sleeps in peace a Hampshire Grenadier, Who caught his death by drinking cold small Beer, Soldiers be wise from his untimely fall
"Third-party" for email but who is which "person"? - Physics Forums
2024年10月19日 — 14,540. It's the same as first, second and third person pronouns. "I" is the first person pronoun, "you" is the second and "he"/"she" is the third. So I make an agreement with you that may involve you choosing to use services provided by him. In fact, I think the "party" terminology does much the same job as pronouns, but primarily in standard ...
