90 degrees Celsius is very hot, withing about 8 hours any food subject to that temperature will be cooked and sterile. Further keeping at that temp will see the food desiccate.
Not very long without water and shade. 55 degrees Celsius is 131 degrees Fahrenheit.
6 degrees Celsius equals 42.8 degrees Fahrenheit. This means that you are likely to wear long sleeves and long pants, with a light to medium warmth jacket.
Opinion 1:No you need to keep them around 72 degrees.Opinion 2:Guinea-pigs can easily handle ranges of temperatures ranging between 20 degrees Celsius (68 degrees Fahrenheit) and 30 degrees Celsius (86 degrees Fahrenheit).In warmer areas where the temperature exceeds 30 degrees Celsius, make sure your guinea pig's cage is always in the shade. They can certainly tolerate weeks of high daytime temperatures, as long as they have fresh water and food daily, but their natural cycle needs the night-time temperatures to drop.
Raw hot food should be cooked at or above 80 degrees C for 8 mins (which kills all germs), after that, hot food should be served strait away, it does not matter what temp the food is after it has been served as long as it is eaten within 20 mins (and does not get below 45 C), then you need to reheat the food for 4 mins at or above 60 C or cool quickly to be stored in the fridge or freezer.
You can't freeze water at 17 degrees Celsius. The freezing point of water is 0 degrees Celsius or 32 degrees Fahrenheit.
it takes about 20 minutes, well that's how long it takes me!
Kelvin, degrees Celsius, or degrees Fahrenheit.
As long as there's enough moisture. You don't mean Celsius, do you?
Ice (from pure water that is) will melt when the temperature rises from 0 degrees Celsius or higher. The only temperature ice will stay ice is 0 degrees Celsius or lower.
Yes. As long as the pressure is below atmospheric pressure.
Foods often spoil because of bacterial waste. However, below about 40 degrees Fahrenheit (about 14 degrees Celsius), bacteria reproduce extremely slowly, and their metabolism slows to the point that they don't consume much of the food, or produce enough waste products to spoil the food. Because it doesn't completely kill all bacteria, food will still spoil after some time. On the other hand, frozen foods are so cold that no bacteria can reproduce, and thus frozen food can virtually last indefinitely if kept well below 32 degrees Fahrenheit (0 degrees Celsius) at all times (freezers are usually about 4 degrees Fahrenheit).
Alcohol will boil at 85 degrees Celsius. Water boils at 100 degrees Celsius. These things always boil at the same temperature, and will continue to boil as long as liquid remains.
