some water vapor released from boiling would condense on the cold spoon as water droplets.
Metal conducts heat better than wood, so a metal spoon will absorb heat more quickly from the boiling water, making it hotter to the touch. On the other hand, wood is a poor conductor of heat, so a wooden spoon will not get as hot as quickly in the same boiling water.
'nothing, it's like putting a spoon in a hot soup' Wrong ^ As the metal spoon is a better conductor of heat than the air the hot water (or soup) and the spoon as a larger surface area with the air (or active sight) it transfers heat to the surrounding faster, thus cooling the hot liquid faster.
My mother didn't, actually, but if one's mother did, it was probably to start cooling it right away to reduce the chance that the glass would crack. The spoon draws away the heat and releases it to the air. So while you may need to pour boiling water over a teabag, it does what it needs to to the teabag and then quickly starts to cool.
Conduction is what transfers the heat in this process. The fast moving particles in the hot electric coil collide with the slow-moving particles in the cool pot. The transfer of the heat causes the pot's particles to move faster. Then the pot's particles collide with the water's particles, which in turn collide with the particles of the spoon. As the particles move faster, the metal spoon becomes hotter.
all the elements that has low boiling point than of the water.
Conduction
Conduction of heat. When the spoon is left in the boiling water, the molecules in the hot water transfer kinetic energy to the metal spoon, causing its temperature to increase.
Metal conducts heat better than wood, so a metal spoon will absorb heat more quickly from the boiling water, making it hotter to the touch. On the other hand, wood is a poor conductor of heat, so a wooden spoon will not get as hot as quickly in the same boiling water.
Conduction is the process that causes thermal energy to move through the metal spoon placed in a pot of boiling water. In conduction, heat is transferred through direct contact between particles in a material. The metal spoon conducts the heat from the boiling water to its other end, thus heating it up as well.
The metal spoon became hot from conducting heat from the boiling water in the pot. Metals are good conductors of heat, so the metal spoon absorbed the heat energy from the water, causing it to become hot to the touch.

It usually takes a minimum of 10 minutes to sterilize items places in boiling water.
When you put a spoon in a pot of boiling water, the agitation caused by the spoon disrupts the formation of bubbles that are necessary for boiling to occur. Without these bubbles, the water temperature doesn't rise quickly enough to reach the boiling point, preventing it from boiling.
My mother didn't, actually, but if one's mother did, it was probably to start cooling it right away to reduce the chance that the glass would crack. The spoon draws away the heat and releases it to the air. So while you may need to pour boiling water over a teabag, it does what it needs to to the teabag and then quickly starts to cool.
When a metal spoon is placed in water, the water exerts an upward buoyant force on the spoon due to the displacement of water. If the force of buoyancy is greater than the weight of the spoon, the spoon may bend due to the imbalance of forces acting on it. This effect is especially noticeable if the spoon is made of a soft or thin metal.
Well, honey, that metal spoon is conducting heat like it's on a mission. When you leave it in that pot of boiling soup, it's basically turning into a mini hot rod. So, if someone's not paying attention and grabs that spoon, they're gonna get a nice little burn as a souvenir.
