CONDUCTION
Like a spoon. I'll try to illustrate it: (LOOK AT THE DOTS_ .______________________ _._____________________ ___.___________________ ______.___________._____ _______________________ ________.________.______
A wooden spoon
Serious advantages doesn't exist.
Metal is a conductor. The spoon heated up from the soup and when the cook touched the spoon, he got burned because the spoon was hot from the soup.
Sensory nerves.
metal transfers heat
If tea starts to boil when a spoon is placed in it, it is likely that the tea has already reached boiling temperature but has nothing to create bubbles with because the glass is so smooth and the smooth is more rough.
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
It usually takes a minimum of 10 minutes to sterilize items places in boiling water.
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.
Conduction
Well, not only three that i know... Keeping a spoon in a boiling pot of water and waiting 5 minuites and touching it again can burn your hand. the heat transfered from the water to the spoon and now the spoon in hot.
