Question

match the type of heat transfer with its example
draggable item → corresponding item
conduction → sunlight warming the earth
convection → metal spoon heating up in a pot of soup
radiation → heating water on the stove

Explanation:

1. Conduction is heat transfer through direct contact between materials. A metal spoon in hot soup gains heat via direct contact with the hot liquid and the pot, so this matches conduction.
2. Convection is heat transfer by movement of fluids (liquids/gases). When heating water on a stove, hot water rises and cool water sinks, creating a circulating current that transfers heat, so this matches convection.
3. Radiation is heat transfer via electromagnetic waves, no medium needed. Sunlight warms Earth by traveling through space as electromagnetic radiation, so this matches radiation.

Answer:

Conduction → metal spoon heating up in a pot of soup
Convection → heating water on the stove
Radiation → sunlight warming the Earth
