Key Questions:

1. Why do hot objects have more energy than cooler ones? How is this energy transferred?
   • heating and thermal equilibrium: temperature difference between 2 objects leading to Energy transfer from the hotter to the cooler one, through - contact (conduction) or - radiation; such transfers tending to reduce the temperature difference;
2. In which direction does heat energy flow?
   • Heat Energy flows from hot objects to cooler ones.
3. When does heat energy stop flowing?
   • Heat Energy stops flowing when objects are the same temperature.
4. What do we call energy transfer through contact?
   • Heat Energy can transfer through contact known as conduction.
5. When does conduction occur?
   • Conduction occurs when fast moving (hot) Particles collide with slower (cooler) Particles.
6. Why does energy transfer in conduction?
   • Energy is passed on as the fast moving Particles slow down as the slower Particles speed up.
