In accord with the second law of thermodynamics which states that heat spontaneously travels from a hotter object to a colder one, when metal touches something hot, the area where it touched something hot, will get warmer because of the increase in energy of the molecules, this warmth will spread throughout all the available metal until the metal and the hot substance it is touching have the same internal energy.
An example of something being heated by conduction is when a metal spoon left in a hot drink becomes hot to the touch due to the transfer of heat from the hot liquid to the metal spoon.
Heat is transferred between a hot and a cold object by conduction through direct contact. When the hot object touches the cold object, kinetic energy from the hot object's particles is transferred to the cold object's particles, causing them to vibrate and increase in temperature until thermal equilibrium is reached.
Yes, a knife can conduct heat because it is made of a material that allows heat to transfer through it. Materials like metal are good conductors of heat, so when a knife comes into contact with something hot, it can transfer that heat to other objects or materials it touches.
When you hand touches the hot handle of a pot. When you touch an ice cube and it melts in your hand. When the spoon touches hot water and the spoon gets hot. When the spoon touches cold ice cream and the ice cream melts.
Rapidly cooling hot metal can cause it to become brittle and more prone to cracking or fracturing. This process, known as quenching, can introduce internal stresses in the metal due to the rapid temperature change. Additionally, the rapid cooling can also affect the metal's microstructure, altering its mechanical properties.

the body turn hot
it reacts by burning where you have touched something
it is conducting the heat away
Retracting a hand if it touches something hot
If it is hot it will most likely explode. If it is cold, it might stratch the outer quartz glass, and then when you try and turn it on the glass will shatter because of the scratch.
like this: You will detract your hand if it touches something hot. LOL
A reflex action.
it melts.
It becomes hot liquid.
An example of something being heated by conduction is when a metal spoon left in a hot drink becomes hot to the touch due to the transfer of heat from the hot liquid to the metal spoon.
The handle of a pot can be made of metal, but it may become hot when in contact with heat. This can potentially burn someone who touches it without protection. Adding a heat-resistant cover or insulation to a metal handle can prevent this issue.
