A metal spoon was placed in a dish of ice cream and became cool. Which correctly describes the heat transfer process that resulted in the cooling of the spoon?
Conduction, because the spoon was in contact with the cold ice cream
Convection, because the spoon was in contact with the cold ice cream
Conduction, because cold air currents affected the temperature of the spoon
Convection, because cold air currents affected the temperature of the spoon
