The parameters for safely cooling food is the same for all cooked potentially hazardous foods:
The chemical composition remain unchanged.
Physical, largely by the evaporation of liquid water in the soup carrying of the heat as water vapor into the air.
Increased surface area increases cooling. Cooling occurs by convection of air above the soup and water vapour loss.
Two main things occur: cooling by evaporation and cooling by convection. There is also some limited cooling by conduction between the bottom of the soup container and the surface it is placed on but this is usually not nearly as significant as the first two methods of heat transfer.
You can use an immersion probe to check the internal temperature of a pot of soup. You can also use a thermocouple with a surface probe to check the internal soup temperature.
Room temperature
... amount of energy in the soup molecules.
105
Well i think the soup will probably stay the same temperature because there is more hot soup then there is cold on the little spoon,so alot of hot temperature will win the the little cold temperature.
60 degrees
That will depend on the size and temperature of the pieces of chicken as well as the temperature of the soup. Cook the chicken until it is 165°F.
You can drink milk, this cools down the pallet or just add cream to the soup.
