It is a common experience that when hot water is poured into a stainless cup, the cup becomes hot after a few minutes as a result of heat transfer from the hot water to the stainless cup; this process of heat transfer is called conduction.
Conduction is a process of heat transfer through a material, with the average position of the particle material remaining the same.
It depends on the difference in temperature of the hot and cold body for conduction to take place. The materials involved must allow heat energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More to pass through them and such materials are called conductors.
A conductor is a substance that allows heat energy to flow through it e.g. most metals are good conductors of heat.
An insulator is a substance that does not allow heat energy to flow through it e.g. wood, plastic, rubber, and wool.
Experiment to show that Water is a Poor Conductor of Heat:
Set up:
Aim:
To demonstrate that water is a poor conductor
