A student stands outside on a sunny day while holding a metal spoon in a pot of hot soup. The student feels heat from the Sun, the spoon becomes hot, and the soup circulates as warmer liquid rises and cooler liquid sinks.
Identify the type of heat transfer occurring in each situation using these words: Conduction, Convection, Radiation.
- Sun warming the student - Radiation
- Heat moving through the metal spoon- Conduction
- Warm and cool soup circulating in the pot- Convection
