Your cafeteria is serving chicken noodle soup today, which it sources from a distributor and then warms up locally in the kitchen. The soup now sits in a large bowl and a server uses a large ladle to fill the soup into the smaller bowls handed out to the students. Consider the following variables:
1. Outside temperature.
2. Duration that the soup was heated before being put in the bowl.
3. Temperature of the soup in a student's bowl.
4. Temperature level to which the soup is warmed up.
5. Insulation of the bowl used for storing the soup.
6. Duration that the soup bowl is open when the server inserts the ladle to serve a student.
