Two methods of transfer of heat are involved in this process: conduction and convection.

In fact, the metal spoon is heated by conduction because the molecules of the boiling water collide with the molecules of the spoon, releasing heat to it; and also by convection, because in the pot of boiling water masses of hot water goes upward and they give their heat to the spoon, then these masses become cooler and they go down, replaced by other masses of hot water.

Answer from: MOONCHILDSUGA

conduction

Explanation:

When metal spoon is placed in a pan of boiling water we can feel that after some time the metal spoon temperature will increase.

Here as we know that here heat is transferred from boiling pan to metal spoon due to which its temperature got increased.

Now there are three possible ways to transfer heat

1. Conduction

2. Convection

3. Radiation

Here radiation do not need any medium to transfer heat so it is not possible here

Convection need either liquid or gas while here we have metal spoon to transfer heat so this is also not possible here

So correct way to transfer heat is CONDUCTION

Answer from: Quest

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf, ℰ, to a battery's terminal voltage, v, current, i, and internal resistance, r, is ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
