The heat energy is transferred from the hob to the metal spoon through conduction; this is where particles that vibrate a lot due to their heat energy then 'pass on' these vibrations to the next adjacent particle which does the same and so on. Metals are a good conductor of heat so that is why the metal spoon gets hot, however, wood is not a good conductor of heat and so the wooden saucepan handle doesn't get hot.
When the sauce-pan is placed onto the gas, something strange happens. The metal spoon inside the sauce-pan starts to heat up. When the water heats up,the particles break away from each other, and the water becomes less dense. But to become less dence the heat has to go somewhere. The water particles rise to the top of the surface and travels along. Then if it meets the top of the metal spoon, the heat that the water particles carry, will be absorbed by the metal spoon. This is conduction in the metal spoon.
Hope this helps

I hope this is more helpful than who-ever answered it last!
Convection to the spoon and conduction through the spoon to the handle
part of the spoon is heated by contact with the hot water .heat is transferred through the metal spoon, particle by paricle, until the entire spoon is hot.
I believe as the tea is in contact with the spoon, the molecules in the spoon start moving around as they are heating up, causing the spoon to become hot.

ENERGY
Mode of energy transfer in fluids is convection.
Assuming you have a cup of hot cocoa, then the heat transfer is by conduction
heat energy is basically kinetc energy (movement energy), since heat is the atoms moving about, the atoms in the gas ring crash into the atoms of the spoon, and cause the atoms in the spoon, eventually the energy (movement), will be evenly spaced between all the atoms in the spoon and gas ring, this transferr is like when a snooker ball hits a triangle of the balls and makes all of them move around
What happens to the chemical energy from gas when it is ignited in gas ring on a hob
metal radiation transmission

because metal utensils can scratch the pans
There is no spoon, so the question is meaningless.
No. Heat can only be transferred to a cold spoon, not the other way round (as there is no heat in a cold spoon to transfer). A simple example is when a cold teaspoon is used to stir a hot cup of tea. When the spoon is withdrawn, it is hot.
Heat (thermal energy) will move between a liquid and a spoon placed in it by the method we call conduction. The thermal energy will be conducted from a hot liquid to a cool spoon by direct contact. There will be a bit of convection in the liquid near the spoon. This is because that liquid (being hotter or cooler than the spoon, depending on the experiment) changes density and either rises or descends. But the point is that direct contact between the liquid and the spoon will set up conditions that allow conduction of the thermal energy.
The heat will transfer to the spoon (if metal).
The transfer of energy is called Energy Transfer
The reason a sppon gets hot when it is in a bowl of hot soup?because heat travels to the spoon to your hand.the more you leave the spoon in the soup,the more heat travels to the spoon and gets hotter and hotter.
