Conduction

Explanation:

We are given that a metal spoon was left in a hot bowl of soup which resulted in heating up of the spoon.

The heating process which is responsible for heating the spoon is conduction method of transferring heat.

Conduction occurred because bowl and spoon were at different temperatures and were in contact with each other. So the heat flowed from the hotter to the cooler object till they both had the same temperature.
