When a high temperature object and a low temperature object are stuck together, the heat of a high temperature object moves to a low place by molecular motion. In this way, the phenomenon that molecules oscillate and transmit heat is called conduction.
Examples of conduction that we can see around us
Gold, silver, iron, aluminum, etc. are well conduct heat. On the other hand, glass, plastic, and wood do not conduct heat well. So if you put a metal spoon and a wooden spoon in hot water and touch it after a while, you will notice that the metal spoon is hot but the wooden spoon is not hot.
When we sit on a metal chair outside on a cold winter day, it feels cold. However, wooden chairs feel less cold. Metal and wooden chairs are at the same temperature. But why does it feel different? This is because the metal transmits heat better than the wood, and the temperature of the body goes down quickly.
