Because metal conducts heat faster than wood. The temperature of the water will be carried up to your hand much more efficiently by the metal spoon than a wooden spoon.
because metal is a conductor which likes hot things
Wood is an insulator. Think about it; when you put a wooden or plastic spoon in boiling water, does it burn your hand? No. This is because it slows the flow of heat from the water to your hand. I do not suggest trying the same thing with a metal spoon, which is a good conductor.
That would depend on what the spoon is made of. A metal spoon conducts heat - that's why cooking utensils are made of metal. We want our pots and pans to conduct heat efficiently from the stove to the food. Put a metal spoon in a boiling pot, and the spoon will very quickly heat up to 190 degrees or more. On the other hand, wood is a very good insulator. You can pick up a wooden spoon from a pot of boiling water and have no fear of burning yourself. The boiling water is at a temperature of 212 degrees fahrenheit, 100 degrees celsius. It cannot get any hotter until the pot boils dry. The wooden spoon will feel neither warm nor cool, because it does not conduct heat either way.
no
Metal is a good conductor. Loosely held electrons can bump into other atoms and help transfer thermal energy.Transfer of heat.

As the metal spoon is a good conductor of heat and because heat travels from a hotter reigion to a colder reigion,the metal spoon will conduct heat away from the hot water and thus,the emty glass will not crack.

Metal is a good conductor of heat. Wood is not a good conductor of heat, although I wouldn't exactly call it an insulator of heat either. If you put a wooden spoon halfway into a pot of hot water, the dry part of the spoon will not get hot even though the wet half will be as hot as the water is, if you leave it in for a while. But if you heat up a wooden spoon and keep it dry, let's say by leaving it on a baking sheet and baking it in the oven along with some cookies, you may be able to grab the spoon and pick it up even though it's hot. There's no way you could do that with a metal spoon because you'd "feel" the heat more with metal. The heat would be conducted from the metal spoon to your skin, but a wooden spoon won't conduct much heat to you.
Metals have specific heats higher than wood.
I think Plastic or wooden spoon is better because wooden spoon wouldn't be hot like the steel ones if we stir it in the boiling water
A wooden spoon
'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.
some water vapor released from boiling would condense on the cold spoon as water droplets.
yes because it will rust
Thanks to lifehacker.com: " If it starts to boil up too high, the spoon will pop the bubbles and keep it from boiling over as quickly, meaning you have more time to get back and turn the heat down. Note that this could warp a wooden spoon, so do it with a utensil you don't want as much. Alternatively, you could use something metal, but you'd have to remove it with an oven mitt because it will become very hot"
