Here's why:

* Conduction is the transfer of heat through direct contact between substances. When you touch the hot metal spoon, the heat energy from the spoon's molecules is transferred to the molecules in your skin.

* Convection involves the transfer of heat through the movement of fluids (liquids or gases). This is not relevant in this scenario.

* Radiation involves the transfer of heat through electromagnetic waves. While the hot spoon might radiate some heat, the primary way heat is transferred to your hand is through conduction.

So, the direct contact between your skin and the hot spoon allows for the conduction of heat energy, making your hand feel hot.
