Summary

• Conduction is the transfer of thermal energy between particles of matter that are touching. Thermal energy is
  always transferred from particles of warmer matter to particles of cooler matter.


• When particles of warmer matter collide with particles of cooler matter, they transfer some of their thermal
  energy to the cooler particles.

Vocabulary

• conduction: Transfer of thermal energy between particles of matter that are touching.
