A metal spoon in a hot cup of tea.

Explanation:

* Conduction is the transfer of heat through direct contact between substances.

* When you place a metal spoon in hot tea, the heat from the tea molecules is transferred to the metal molecules of the spoon.

* The molecules in the spoon vibrate faster due to this energy transfer, making the spoon feel hot.

Other examples of conduction:

* A frying pan on a stovetop: Heat from the stovetop burner is conducted to the metal pan, then to the food inside.

* A hot iron on fabric: The heat from the iron is transferred to the fabric through direct contact.

* Your hand on a hot stove: The heat from the stovetop is conducted to your hand, causing a painful burn.
