- Thermal conduction is when materials conduct heat through those materials through collision of particles
- Thermal conduction is when heat flows from warmer object to cooler object
- Therefore, thermal conduction is a heat exchange process involving the collision of particles

So, thermal conduction is a heat exchange process involving the collision of particles
