Answer
- Putting the soup in a thermos- Covering the top of the bowl
Explanation
To keep the soup warm longer, we need to minimize heat loss. Using a thermos and covering the bowl reduce heat transfer. Placing the bowl on a cold surface or near an open window would increase heat loss, and stirring with a metal spoon would conduct heat away from the soup.
