Final answer:
The correct energy transformations shown in the photo of the campfire are:
chemical energy → thermal energy
Step-by-step explanation:
In the process of a campfire, the burning of wood involves a chemical reaction known as combustion. Wood contains chemical energy stored in its molecular structure. As the wood combusts, this chemical energy is converted into thermal energy, resulting in the emission of heat and light. The flames and the glowing embers of the fire are manifestations of the thermal energy produced through the combustion of wood.
Chemical energy is stored within the molecular bonds of the wood, primarily in the form of potential energy. During combustion, these chemical bonds break, and new bonds are formed, releasing energy in the process. The released energy manifests as heat, raising the temperature of the surroundings, and light, producing the characteristic flames and glow of a fire.
It's important to note that the other options involve different energy transformations. For instance, option 1) thermal energy → chemical energy is not accurate because it suggests the reverse process of photosynthesis, where plants convert sunlight into chemical energy. The correct understanding of the energy transformations in a campfire invol
