Describe, in terms of the motion of particles in an object, how heat conduction transfers energy between objects or from one part of an object to another part at a lower temperature.

• Heat conduction involves the transfer of energy through the motion of particles.

• Heat conduction occurs only in liquids.

• Heat conduction requires a medium to transfer energy.

• Heat conduction is the transfer of energy through electromagnetic waves.
