Why does a metal spoon get hot in drink?

When a metal spoon is placed in a hot drink, heat from the drink is transferred to the spoon through conduction. Conduction is the transfer of heat energy between two objects in contact with each other. Metals, like the metal spoon, are good conductors of heat, meaning they can transfer heat energy quickly and efficiently.

The rate of heat transfer depends on several factors, including the surface areas of the two objects in contact, the temperature difference between the objects, and the thermal conductivity of the materials. In the case of the metal spoon, the large surface area of the spoon means that there is more contact between the spoon and the hot drink, allowing for a faster transfer of heat. Additionally, the high thermal conductivity of metal means that the heat is transferred very efficiently through the spoon.

So, when you place a metal spoon in a hot drink, the temperature difference between the drink and the spoon creates a flow of heat energy from the drink into the spoon. As the spoon absorbs this heat, its temperature increases and it becomes hot to the touch.
