A metal spoon is left standing in a hot drink and the handle becomes warm. Which process is this?
AConduction
BConvection
CRadiation
DEvaporation
Answer & Solution
Correct answer: A. Conduction
1. The particles at the hot end of the spoon gain energy and vibrate faster.
2. They bump into neighbouring particles and pass some energy along.
3. Energy travels along the spoon this way until the handle warms up.
4. This kind of transfer through a touching material is called conduction.
