In what type of material does conduction happen?
describe how energy transfer may take place by conduction.
explain the role of conduction in everyday phenomena.
explain how insulation is used to reduce energy transfers from conduction.
Conduction is the transfer of heat from one object to another through direct contact. When a hotter object is placed in contact with a colder object, heat will transfer from the hotter object to the colder object. Examples of conduction are boiling water on the stove and heating a home with radiators.
Conduction: Heat Transfer Through Matter
Conduction is the transfer of energy in the form of heat energy through a medium. The speed of conduction is affected by the type of material in which it is travelling. It is possible to measure the rate of conduction in materials by using a special instrument called a thermal conductivity meter.

Which material is a good conductor of heat?
What happens to the particles in a solid when heat is conducted?
- Particles vibrate and pass on energy to neighboring particles.
- Particles break apart and become free electrons.
- Particles evaporate into gas form.
