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.
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.
At 10 degrees Celsius, it's best to wear layers to stay warm. Start with a base layer like a long-sleeve shirt, add a sweater or light jacket, and finish with a coat or jacket to protect against the cool temperature. Don't forget a scarf, gloves, and a hat to keep extremities warm.
it takes about 20 minutes, well that's how long it takes me!
Yes, ice can be colder than 0 degrees Celsius if it is in a location where the surrounding temperature is below freezing. Ice can exist at temperatures below 0 degrees Celsius as long as the environment is cold enough to keep it frozen.
Kelvin, degrees Celsius, or degrees Fahrenheit.
Yes, evaporation can occur at 0 degrees Celsius, but at a slower rate compared to higher temperatures. As long as there is enough heat energy for molecules to break free from the liquid surface, evaporation can still take place.
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.
"Cold" could mean anything. To me, cold might be 10 degrees Celsius, while someone else sees "cold" as 1 degree Celsius. In science, nothing is ever described as cold, because a questions that always arise are "how cold? 20 degrees Celsius? 0 degrees Celsius? -100 degrees Celsius?"
Water evaporates at any temperature above 0 degrees Celsius (32 degrees Fahrenheit), as long as there is enough energy to break the hydrogen bonds. Water freezes at 0 degrees Celsius (32 degrees Fahrenheit), when the energy of the water molecules reduces enough for them to form a crystalline structure.
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).
