A copper spoon is dipped in hot water. What happens to its other end?
It becomes hot by conduction.
The correct answer is Option 2: It becomes hot by conduction.
When a copper spoon is dipped in hot water, the end of the spoon in the water absorbs heat from the water. Copper is a good conductor of heat. This means that heat energy readily flows through the metal. The heat energy is transferred from the hot end of the spoon to the other end through the process of conduction. Conduction is the transfer of heat through a material without the movement of the material itself. The molecules at the hot end vibrate more vigorously, transferring their energy to neighboring molecules, and this continues along the spoon until the other end also becomes warmer.
In contrast, convection involves the movement of heated fluid (like water or air) to transfer heat. This mechanism doesn't directly apply to the spoon itself, even though the water around the spoon might be heated via convection.
