Question

The figure below represents the energy in the chemical bonds in a pile of firewood. Replace the “X”s with the appropriate number (the first one is done for you): (10 pts per X)

1. A pile of cold (low energy) ashes
2. A neatly stacked pile of wood
3. A roaring fire
4. Burning kindling begins to add energy to the pile
5. A pile of hot (but cooling) coals

Answer 1

To answer your question effectively, I would need to know the specific values or context represented by the "X" in the figure you referenced. However, I can provide a general approach based on common chemical energy concepts in a firewood scenario.

If we assume a basic energy hierarchy based on typical combustion processes:

1. A pile of cold (low energy) ashes - **1** (indicating the lowest energy state)
2. A neatly stacked pile of wood - **5** (indicating some energy due to the wood's chemical potential)
3. A roaring fire - **10** (the peak energy state during combustion)
4. Burning kindling begins to add energy to the pile - **7** (the kindling is releasing energy)
5. A pile of hot (but cooling) coals - **8** (still contains significant energy, though cooling)

If this does not match the expected context of your question, please provide the figure or additional details for a more tailored response!
