'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.
The metal spoon is a better thermal conductor.
The spoon gets hot because metals are good conductors . Meaning that heat, cold, electricity move through them, certain metals are better than others. Even a wood spoon will conduct if it is soaked in water, of course in this case the water is the conductor.
Metals are generally good conductors of heat. That is, heat moves through the metal easily. Wooden, plastic, bone, etc are poor conductors of heat. So, the heat moves from the hot area (fire, boiling liquid, etc.) throughout the spoon to the handle making it hot, but does not do this with wooden, etc. spoons.
You drop a metal spoon at 20o C into the pot of boiling water (at 100o C if barometric pressure is 1 atm)
and you will have heat transfer by convection from
the water to the spoon surface, and heat transfer within the solid spoon by
conduction.
the temperature increases because metal spoon is good contact of heat then a plastic spoon.
because its metal which is cooler than plastic
A metal spoon gets hot as it is a conductor of heat. Conducters pass heat freely through them while insulators (wool, wood, plastic ect) don't.
Because the metal spoon is an insulator the heat of the hot chocolate is transferred to the spoon.
The heat will transfer to the spoon (if metal).
some water vapor released from boiling would condense on the cold spoon as water droplets.
Conduction.
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.
I did this experiment for school and sugar is the most soluble in boiling hot water. this was my experiment: Sugar: - I had to stir each tea spoon of sugar for quite a while but amazingly it was the most soluble out of all the substances I put in the boiling hot water. I put 7 teaspoons of sugar into half a glass of boiling hot water. Salt: - on the 1st tea spoon the salt dissolved really quickly so I thought that it would be the most soluble but at the 3rd tea spoon it wouldn't dissolve anymore. hope this helps...
metal
Conduction
an example of thermal conduction
Metal is a good conductor. Loosely held electrons can bump into other atoms and help transfer thermal energy.Transfer of heat.
because metal is a conductor which likes hot things
some water vapor released from boiling would condense on the cold spoon as water droplets.
Sensory nerves.
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.
The heat will transfer to the spoon (if metal).
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.
the metal.
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
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.
