The forces....do I have this right? So, I'm not in any way trained in any type of physics...so I'm sorry for the very basic way of explaining my question. Energy released from burning firewood (for example). The way I think of this (and would explain it to someone) is that a chemical reaction is occurring, where hydrocarbons are being broken into their individual parts...that being hydrogen and carbon. The smoke I see is the carbon (and other stuff like water vapor). The heat I feel are the molecular bonds (energy) which were previously holding carbon and hydrogen together in a molecular fashion. Question/s- Is this incorrect....or essentially how it is working? Also.....where is the hydrogen going? Is that the fuel for the flame I see, combusting with the oxidizer in the air? Is the energy released from the weak force?? Energy released from an "atomic" (let's use fission for the example) explosion- Is the energy that is released a manifestation of the energy (strong force?) contained within the bonds which previously (pre-fission) held the atomic structure/parts (neutron, proton, electron) together? Basically, I've always had it reasoned out in my head that fire/combustion is the release of the molecular bonds (previously holding the molecules together), while fission and fusion are releasing atomic bonds (previously holding the sub-atomic particles together). Am I out in left field?? I started thinking and reading about the weak and strong forces....which made me question the basic assumptions I have long kept....??
