Bacteria causes food to rot and not the metals in the spoon. I think it matters what food you eat with it though, and if you sterilized the spoon or just washed it in hot water. Never leave something known to be inside the mouth in a soup or food set for storage as bacterias only need time to overwhelm the food.
That depends on the pan. If the pan is covered with a non-stick coating such as Teflon, then scratches caused by a metal utensil can degrade - and even ruin - the non-stick finish. Of course, even wooden or plastic tools can damage the finish if you are not careful.
If the pan is steel or cast iron, then a metal utensil will not damage it.
A metal spoon touching a hot pan. The pan heats the spoon. The spoon serves as a conductor of heat. This is an example of conduction.
Same reason you don`t stick metal into a toaster
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.
Yes, a tin pan will heat water faster than a plastic pan because metal conducts heat more efficiently than plastic. The heat is able to transfer more quickly from the heat source to the water in a tin pan compared to a plastic pan.
There is no problem using a metal spoon to scoop honey.
A metal spoon - plastic does not conduct electricity
Touching a hot pan and feeling the heat transferred from the pan to your hand. Placing a metal spoon in a hot cup of coffee and feeling the spoon get warm as heat is conducted from the coffee to the spoon. Walking on hot sand at the beach and feeling the heat transfer from the sand to the soles of your feet.
I doubt it is the soup, it is probably your cutlery, or the cooking implements (like spoon or pan) that you use to make the soup.
because metal is bindable and wood is a solid
a metal spoon melts faster because the law of chorny's
