Pasteur said that heating the wine at about 120°F would make sure that the wine would not turn sour, so the option is A.

Why can't elements be separated into smaller parts using chemical means? Too much energy is required, since you'd have to break them down into protons, neutrons, and electrons. You can get this much energy together with nuclear reactions, but not by chemical means.
Answer:
1. Organic Alcohol
2. Ester (specifically acetate ester)
3. Organic Alcohol
4. Carboxylic acid
5. Ketone
6. Ether
7. Amine
Explanation:
You can tell what type it is both from the nomenclature and looking at the functional group on the molecular structure. Hope this helps!
Answer: (Assuming we’re going by degrees Fahrenheit) I’d say 140.
Explanation: -40 would be beyond freezing point for water which is 32 degrees Fahrenheit and 40 would nearly be freezing point. For water to transform into its gas phase, the temperature would need to be greater. Therefore, 140 degrees Fahrenheit makes the most sense.
Although I did search it up and 212 degrees Fahrenheit (100 degrees Celsius) is the proven temperature at which water transforms into water vapor so... not sure if there’s more to the question or I’m interpreting the question wrong.
