Yes. This is okay to do. Since you are blanching them. This process will kill any bacteria they may have standing at room temperature.
Up to 14 days.
Your question is confusing. The Apollo astronauts who landed on the Moon carried life support units on their backs. These packs they carried let the breath and kept their blood from boiling or freezing.
Insulin does not have a boiling point, as it is a protein molecule that will denature (lose its structure and function) well before reaching a temperature close to boiling. Insulin is typically stored in a refrigerator to maintain its stability and effectiveness.
It kept them from freezing in the cold days.
Food is safe if managed with sanitary procedures. It is important to wash your food before preparing recipes. The surfaces used to prepare food should be kept clean and wiped to prevent spreading of bacteria.
It was important because it kept colonist from freezing and during.
Bread can be kept at room temperature for short periods, typically up to a few days, as long as it is stored in a cool, dry place and in an airtight container to prevent it from drying out or becoming stale. However, for longer storage, refrigeration is not recommended as it can accelerate staling; instead, freezing is a better option. To maintain freshness, consider slicing the bread before freezing and toasting slices as needed.
1 - 2 days as per US government standards but for personal safety, as short of time as possible. See the related link for more information.
Protect from what. An ice cube with melt unless kept at or below freezing.
As I recall from class way back when: The salt raises the boiling / freezing point of the water. There by melting the ice because it is no longer being kept at its freezing temp. It would also work for fresh water (with no salt in) as the water is warmer than the ice (i.e above zero) when the two are mixed the water will warm the ice cubes until they melt. (or all the water freezes)
Aviation fuel is kept from freezing from a additive called FSII, Fuel system icing inhibitor which is added in the fuel at approx 0.015%. hope this helps, let me know if you would like more info and ill go more in detail with it, Brent
If a thermometer is not kept moist with condensate, it may provide inaccurate readings of temperature. In boiling point measurements, moisture helps to ensure accurate thermal contact and enhances heat transfer. Without this moisture, the thermometer may not fully equilibrate with the boiling liquid, leading to a higher or lower recorded boiling point than the actual temperature. Consequently, the absence of condensate can result in erroneous data when determining boiling points.
