How long it will take for raw meat to spoil will depend upon the conditions in which it is stored and it's use by date. If the meat is left out at room temperature on a warm day, it will likely spoil in several hours but on a cool day, it could take 24 hours to spoil. Stored in a refrigerator, raw meat would take 3 to 4 days to spoil if it is still within its use by date.
Not long
Depends on the original temperature, but from frozen, approximally 24 hours.
Ice cream at room temperature melts.
I would estimate a two hour limit for keeping yogurt at room temperature. Personally, I take it out of the refrigerator and eat it immediately. I see no need to keep it at room temperature.
That really depends on the temperature of the room it's in.
It takes about two hours.
6 to 7 days if your room is at 19 degrees.
It is a rather long process, but I will make it short. Food, at room temperature, will actually depend on what kind of food it is. With this in mind, it will determine how long it will take for that food to mold (spoil). Keeping it in a refrigerator or freezer will slow this process down sharply by limiting the movement of the food's molecular structure which in turn will make much less room for mold to start growing. However, it is not halted completely, and any and all foods will eventually spoil. Well, those foods that say will NEVER spoil are terribly bad for you, as they are loaded with preservatives.
Most refrigerators are in the 40degree range, the standard room temperature is 70 degrees. To bring an 8 ounce brick of cream cheese to room temperature should take 30-45 minutes.
I have no idea at all what your question means. Take a piece of iron and put it in a room whose temperature is 32 degrees, and before long the iron's temperature will be 32 degrees. Put a piece of iron into a room that is at 105 degrees, and before long the iron's temperature will be 105 degrees.
That entirely depends on quantity, the starting temperature and the density, but an average size wheel should reach room temperature from the refrigerator in around 40 mins.
